can webhosting and social networking work together?

im using wp version 4.1
i have an idea of making my domain a social networking site and my multisite hosting company as a "subsite" will this work?
all i want is to receive paypal chain payments(marketpress) for a percentage of what they make on their website example: as:
with social networking plugins and

"" (site not made yet) as:
how do i set it up with (mycred,marketpress,membership,prosites,buddypress,etc)

which plugins do i need(wpmudev plugins and "free" third party plugins)
i will be offering with wp plugin + mycred (still being customized)(pay per view) (i can only offer as a subdomain wildcard it cannot be offered with domain mapping)

which plugins do i need to be activated with network activated(for hosting ,multisite network security and performance)

which plugins do i need just for my main site only (social networking)
