We have ~15 websites that needs to be upgraded to the latest virtuemart version currently available without damaging the current workflow of the e-commerce process (there is a one page checkout component and credit card component that should work on the latest virtuemart versions too).
Each website has a different version and was built by a different contractor so each website site is unique with it's own issues to resolve.
We need a complete and total offer for this complex upgrade project.
I'm a front end developer myself so each step will be checked by me till we are fully content with the process.
The new and improved versions will be built on our servers so we can track each step as you make it.
Please apply only if you are familiar with Joomla and virtuemart override methods and is a php expert.
