I need a HTML5 Interactive Map coded. NO FLASH!

I need an interactive map coded and developed. It has to be responsive as our Joomla template is a responsive design.

The code must also be HTML5 - so it works across devices (so no flash)

We like the easyJet Route Map but we want it to be more simple.

Map must not have the whole world - so we want to rule out Google Maps - this is not the solution that we want.

Our company is a International Container and Vehicle Shipping company and operates from Ports, mainly north and east african seas.

The interactive map is required to demonstrate the location of each Shipping/Container Ports.

A good example that I have found is the Easyjet Route Map:

The interactive map must be coded via HTML and CSS and match our colour scheme.

Feel free to ask me any questions.

There isn't a specific deadline for this project, but we are looking to have this developed in the next week or so.

Looking forward to your proposals.
