Where can i find clean(or mostly clean) rap/party mixes?

I'm throwin' a big party and need to know where i can find some MOSTLY clean party and rap songs. I love black eyed pees and 50 cent and all that, but hardly any of it's clean. If i hire a DJ will he be able to keep most of it clean? The main reason is it is a public party + there will be alot of Christian's there. Thanks in advance.
