Prop. deals

As you probably know, prop deals are some of the most efficient means to reward poker players.
A propping setup however, is a much more complicated thing than just about any other bonus or promotions system. You'll earn a lot of cash back on the rake you generate, sometimes even 120%, which is basically the equivalent of getting paid to play poker, but there are bunch of obligations you have to undertake.

You'll be limited by the stakes you're allowed to play at, by the number of people at the table, by the types of games, and a few more factors. Being a prop player is not even remotely funny, so you should treat the whole thing accordingly.
On the other hand, these prop deals can be extremely lucrative for a good poker player, there's some pretty hot EV+ in them.
Many poker sites out there offer prop deals (can't tell you their names though, until you read and accept the terms and conditions) some are better, with less restrictions, others are tougher, but with a bigger cash-back percentage. Check them out below, choose one and sign up.
