where to go to rent out my servers?

i've got five decently powerful servers collocated in California.I would like to rent them out to people to cover collocation costs. Since they are in my name, ofc I wouldn't want to rent them out to black hatters, I'm posting here just for directions and advice. Most people on here are pretty computer and internet savvy. So I'm asking you guys, are there any websites or forums that have like marketplaces where I can rent out my servers? Thanks. If you don't know of any, can you guys tell me…
