Adding features to my site

I purchased a php script called incentivesitescript. It rewards members with cash for completing offers. The script is pretty generic, but I would like to add a few things. I am not that handy with php, thus my post here. My site is [login to view URL] to give you an idea of the layout. I would like to add the following to my site: A Terms of Service section A tell a friend feature or referrall script (please quote price for each) On my offers page I would like to add a way to search the offers (highest paying, 100% Free, etc.) Also on the offers page, if a member marks the offer as done I would like for it to be removed from thier offers page or atleast some way for them to distinguish they have marked it as done, such as replacing the done button with a check mark. On the members pending and completed page I want the offer name to show instead of just offer In my admin panel I would like the following implemented: I would like the name of the offer to show when marked as done by the member instead of just offer. I would like a delete a member feature I would like the pending offers sorted by member name All bids are welcome. If you have additional questions just ask. Thanks.
