If you are not eligible for NHS treatment, and time is limited, you may want to look into going abroad for IVF. My wife and I are headed to a clinic in Norway for a consult in a few weeks. Even with flights and accommodation we are looking at about £3000 all in, and they will work around us. My wife found a few other clinics in the Czech Republic as well, but we were not able to use them (apparently in the Czech Republic only straight couples may have fertility treatment, who knew).
