Attornwy fee for drafting a joint venture contract

what's the typical fee most people have paid or are willing to pay for legal fees? My attorney wants $2000 to create a joint venture contract for private investors to tie their money as a lien against love of my houses. He will also record the lien. It seems a little steep. My other concern is that he has never done this specific type of contract. I'm trying to be open minded because we all start somewhere. Could use some words of wisdom here.
