FL Studio, Reason and Logic are all awesome programs for music. However...
Music for games is a really deep rabbit hole. Just like you won't be an amazing artist over night, you won't be a world class sound designer. There are lots of communities of musicians on the net, your best bet is to post an ad on one of those sites to try to find a musician that will work either pro bono or on a royalty scheme of some sort.
Best of luck with it all!
