IuI cost

Hi. We live down in Groton, CT and are shopping around for a clinic that does IUI. Been TTC 2+ years w no luck. Dr say that's our next step. Our insurance doesn't cover any of it. So it will be out of pocket.  We'd be willing to drive to Boston, Rhode Island or what ever. Has anyone paid out of pocket for theirs? How much? Was it a success? Any info would be great :) thanks
