If I were you I would try to stick to a rugged indica dominate strain, as mutt said. Something like northern lights, afgani, or any indica dominate plants.
Try to stay away from sativa dominated plant initially because they are harder to grow, in general because they usually have a longer flowering period. The one exception would be skunk #1, as that is an easy strain to grow and is recommended for beginners.
Honestly i think that Mutt gave you the best advice right off, Northern lights is the most lucrative plant to grow for a beginner. this will probably give you the best quality + quantity for your first grow, because it is a very strong plant that can take a lot of abuse.
Also northern lights is very potent and has a very unique high. That would be an excellent choice for you,IMHO
