Joomla custom modifications and bug fixes (ongoing work)

We have a Joomla community web site that is heavily modified and uses several custom made components and modules. We use two instances of CB (will probably add 1 or two more for more usergroups) We also use aMember subscription system with Joomla integration that also needs some improvements and bug fixes. We need developers that can deliver quickly. We will supply you with a list of specs and once you are finished we will send the next list. This will be an ongoing projects 10-20 hours and most probably more hours for the next few months. Ignore the budget for this project. Please provide your hourly rate and let us know if you can start immediately (ASAP). Thanks you in advance for your bid.
