For Fairness

  • Inquiries about web sites with illegal contents, such as adult, violence, racial and criminal, as well as sensitive contents such as religious, political, military, legal and medical will be rejected.
  • Advertisement links and share links to "social networks" only supported if under control and after confirmation of the nature of the linked sites. In most cases, linked sites are neither under Requio's control nor under our clients'. Sadly, the internet is not a safe place.
  • Simple and easy to client-maintain websites compatible with a wide range of desktop and mobile devices naturally expect compromises with regard to page design which is a physical limitation. Nowadays search engines, such as Google give ranking preference to web sites which scale well on mobile devices.
  • You are more than welcome to maintain your website in-house after delivery. However, you would need to assign a colleague with at least basic web programming skills, otherwise the site will remain unattended or ends up in a broken look. Requio can assist you with a brief training.


Requio offers contemporary web design & development scaling on many devices with a single code base.

Search engines reward "responsive designs" with better ranking.

Responsive designs help save cost as there is no need for multiple websites for each target device.

Public Web Sites

A website to promote your organization, merchandises, ideas, yourself...

This is a standard website for your public internet presence. A basic concept for a small company typically comprises 5 to 7 pages, and carries the lowest price tag.


Company internal websites restricted to employees and trade partners only...

Most companies have need for a platform on which they can share information with targeted colleagues or trading partners. It is basically an ID and paswword protected website.

Management Systems

Database-driven merchandise stock control, school classes tracking system...

Keeping track and history of products and services is a rewarding task, made easy with a powerful database engine and tailored user interface. Requio employs PHP/SQL.


The most popular Content Management System with a flat learning curve...

Requio builds the template for you, and after installation on your server you can start populating your website with contents and maintain your site yourself, saving maintenance fees. The drawback is that WordPress is a popular hacker target.

Android Applications

Compact applications to support your ideas, products and services...

Either as a primary or a secondary promotion tool mobile applications reach out to more people. Requio currently supports Android devices only.


Complementary use of scripting languages: HTML, CSS, PHP, SQL, JavaScript, jQuery...

Practical hints for saving money


Less is More

A simple site is less expensive, uncluttered, easy to navigate and provides quick access to sought after information. But this is not all. Most clients wish to maintain their new site in-house without learning website scripting languages, in that a simple structure helps understand where text and images can be easily added, exchanged or deleted, quickly and painlessly.

Actually, all you need for editing a simple website is a text editor, like Notepad or Wordpad that comes with Windows. Maintenance of a complex website is a time-consuming process, while extra time for maintenance is what most companies cannot afford.


Lower the development fee.

  • you have a clear idea/vision/concept of your web site
  • you do not require several design suggestions
  • you provide most photos/illustrations
  • you provide most/all page texts
  • you agree to simple programming allowing easy maintenance by yourself


Not you, but your target audience must love your site.

  • Efficient simplicity, device responsive
  • Minimum, better no flash and animation
  • Comprehensive structure uncluttered contents
  • Abundant 'white space' on pages
  • Intuitive navigation
  • Fast page display
  • Young mood but with authority and gravitas but not too conservative of senior professionals.

Please resize the window to a narrow width and pull it back to larger sizes. You will see that text and images are scaled while columns are arranged vertically on narrow screens. The menu bar, too, is converted to suit smart phone screens. Responsive design layouts must be simple in order to be responsive on most kind of mobile devices. In turn you will be rewarded with lower cost, a larger audience and better positioning in search results.
