Which plugin?

Hi all. I am in a need to make a software catalog for our project.
We are making a project buyappsforlife, where software makers can contribute from each sale of software to help women who has breast cancer in armenia to buy a treatment medicine Herceptin, which is not free over there and costs 3000$ for each ampula(treatment is from 12 amupula) …
So I need a make catalof of mobile apps and software , with tagging, categorisation, search, and availability to link .

For example for Apps that has version for Iphone and Andorid I need 2 links to enter for others one and so on.

Also I need to enter for each peace of software how much it cost, how much they contribute for each sales made, if they contribute directly or we are affiliated with it, and we get %age. Also would be nice to give ability developers add software directly from website to catalog, we review and activate.
Something like very advanced catalog of software and their developers(vendors?). Would be nice if users can register and also somehow donate for project, getting badges depending on support level by Paypal…. Could you hint on what plugins we could connect it fastly?
