i don't know any sites which will tell you the compatability of those signs...
what kind of compatability were you wanting to know about?
if it's sexual compatability, you should base that on your Mars sign, anything to do with learning on your Mercury sign, socially or romantically is your Venus sign... if you don't know any of these, this site will come in handy:

your rising sign is only your public persona. your moon is the way you nurture/like to be nurtured.
