Heck, if I lived within an hour's drive of you, I'd install a toilet for you for $200 any day of the week, provided by install, you don't mean running the water line and drain line, and you just mean remove the old toilet, put together the new toilet, install the new toilet. As everyone above said, it's a 30 minute job. OP, I think that if you watched one or two Youtube videos, you would realize that you could do it yourself. Heck, I think the only tools you'd need is a crescent wrench and screwdriver. Oh, and a little hacksaw blade to shorten the bolts after installing it so you can stick those little white caps on them, though some brands of the bolts actually are made that you can bend above a certain point and the excess length snaps off. Seriously, OP - I'd trust a kid to install a toilet if he watched a couple of videos first to learn how to do it.
Re: someone mentioned the flange above - they make a metal replacement flange to repair bad flanges. I think HD carries them, and likely Lowes or any other plumbing supplier. I can't remember who I helped, but we had to stick one of those in, and it worked like a charm.
