Project Description:
We need to upgrade our social engine based website from version 4.1.7 to the latest social engine version.

we have had a host of modifications done on the website and most of these modifications are not in a plugin form. unfortunately the earlier vendor made a lot of these mods in the core itself.

the upgrade will be done on a development site and after testing the functioning there, it will have to be migrated to the live site.

the list of mods is attached as an excel sheet (which have been done in the website) -

kindly give a cost which is time bound and not endless.

Also i request that only those people apply who have a intense knowledge of SOCIAL ENGINE.

Skills required:
MySQL, PHP, Social Engine
