Migrate Joomla 1.5 sites to 2.5

I have a number of Joomla 1.5 websites which I need to migrate to Joomla 2.5. They vary from simple sites to fairly complex with different extensions which may or may not be compatible with Joomla 2.5. All sites are hosted on Linux servers with full access to cPanel, migrations are taking place on the same hosting. I am looking for assistance to carry out these migrations. Initially I am looking for bids to carry out a fairly straightforward migration with minimal extensions and a template that has already been converted to be J2.5 compatible. If the work on this site migration is performed well I will be looking to employ the successful bidder to carry out further migrations as well. For the avoidance of doubt, this project is for bids on the following work: - Carry out migration of ONE Joomla 1.5 website to Joomla 2.5 - Ensure site performs and displays correctly after migration before being made live and replacing current site - If necessary customise template code to ensure compatibility (though template will be converted in advance to be J2.5 compatible) Any questions, please feel free to ask.
