You should give it a try to remove it yourself. If the bolt is not rusted badly it may not be as bad as you think. Use a good sharp center punch and mark as close to the center of the broken bolt as possible. Use good ("made in USA"), sharp, new drill bits and start with about 3/32 drill bit and drill about an inch deep or until it breaks out the bottom of the bolt. Slowly work your way up in size until you are just starting to touch the threads in the head. Apply a little heat around the outside of the bolt. The idea being to expand the metal around the bolt to help loosen it. Use the biggest extractor you can get about into the new hole but it must stick into the hole about 1/4 inch deep minimum. This is a very slow process, but they can be removed. If you get in a hurry you will break the extractor off and that would be very bad. The extractor needs to be a very high quality, "made in the USA" item for the best chance for it to be successful. Good Luck!
