For some reason .biz does not have a strong record of domain names sold. I would spend a little time developing a mini site or blog giving end uers some ideas.
Undeveloped = high $xx to low $xxx's
Developed = mid $xxx's to high $xxx's
You have a good name, but I wouldn't sell any .biz's right now, wait a little while until big domain marketplaces and communities shed some light on them like specialized auctions or sticky news.
