My 2 bits:
Offer an agent a fixed amount to consult.

Make sure its someone who can address all the concerns you have that can be put in words (non-verbal terror is not really fixable).

Make sure they can talk about underlying economics and the relevant micro-market without sounding like a salesman douche.

Make it clear you will pay them whether or not a sale comes out of this.

That will keep the conversation honest and fair.
You might not like what you hear but it will be relatively less likely to get you screwed.

Good luck dude.
