Any lawyers on here?

I am going to be paying a lawyer soon to assist in legal counsel for my new start-up. First he is going to hammer out all the legal issues, but what else should he be doing. I'm going to be paying him a $4000 retainer. So what types of documents/ agreements should he be writing up. I am very new to this so please don't take this for naivety. I want to be knowledgable so I don't get shaken down by the lawyer. He needs to work for every penny of the retainer.

If it helps, I'm going to be developing an online website similar to a daily fantasy type of platform.

Any advice would be much appreciated. Thanks

$4,000 retainer
