How much would it cost to fix my snaggletooth?

My teeth are completely straight except for one tooth (third from the front which overlaps the one next to it) which is a bit crowded (I think it's called snaggletooth). I've asked in Orthodontic Clinics but most of them tell me I have to have a consultation to find out the price, the consultation alone costs $200 and I don't want to pay that much unless I can definitely afford to get the work done. Has anyone had similar work done or know approximate prices I could expect to pay to have this fixed??
