help with domain name

I guess its about time I started thinking about a web site. The domain name I wanted for my company has already been taken. My company name is smith lawn service, somebody already has smithlawnservice.com. I could do .biz or .net, but not sure, it seems most people perfer .com. I could do something like smith-lawn-service.com, again not sure how that will go over, most people would probably forget the hyphen's. Give me some ideas.

thanks
