Virtuemart on Joomla / Site Completion and Tidy Up

We need an experienced Joomla/Virtuemart engineer to assist in completing the implementation of our newest website which sells satellite internet broadband.
The site is almost complete and is currently able to take transactions through Paypal however it is required that the site be completed with clear directions to the visitors shopping cart as well as the checkout process be streamlined. Once this is complete we would look to the appointed contractor to carry out any future work that is required as well as to advise on potential improvements that can be made to the site. Due to the nature of the work, we will look at bids from contractors with a track record more favourably however other bids will be considered on their individual merits. The site in question is apogeeinternet.co.uk.
