How do I successfully hire full time IM staff?

Has anyone got any ideas on how to hire good staff in your IM based affiliate business?

Here's our constant dilemma. I'm hoping someone else can give me some ideas on how to find staff, train them to be autonomous and skilled, yet not giving them the tools to go away and build their own business.

This has been our constant battle. We've hired quite a few people to work full time in our office. They tend to either be hopeless, or if they are good, they see how much money you can make once you have the skills (that we give them) and they leave to start their own business.

Has anyone managed to hire someone successfully into a key position. Designers, programmers and content writers are fine. It's the more critical management positions that are hard to fill.

We've tried bonuses with some success, however, most people don't realize the costs to running a decent sized business and just see the affiliate commissions coming in and don't think much further beyond that.

Any ideas? I'd love to hear them.

Oh... if you can give me any ideas on where to find good staff, I'd appreciate that as well.
