Looking for an Animal Shelter Script

I am looking for a script (wordpress theme or php script) for an animal shelter where everyone, meaning all site members and website admins - can also sell their own physical and digital products, offer their own pets for sale and their own rescued animals for adoption, and everyone can solicit donations without getting the website admins involved, and also where everyone can interact with each other, like in Facebook. Any script suggestions, other than hiring a developer to create such a script?

You have get answer on last sentence.

I do not see any answer, where is it?

Hire developer to make a script. You will not find out of box solution.
