Need contract attorney for a quick review

I am looking for a contract attorney to provide legal advice to me concerning what is basically a rental agreement. I vend at holiday markets in major cities. There are some changes to a contract this year, and I need an attorney to read it over, and tell me if it is ok, or if I would be foolish to sign it, as well as suggest potential revisions. My main concern is a new strongly worded hold-harmless issue, but I would like all 5 pages reviewed. US based bids only please.
