The typical alternative to an expensive degree, is to look at certification courses, or skills updating workshops, or conferences/conventions in your specialty. Further, look at serving as an 'intern' where you offer to work at less than professional pay or no pay at all for limited period, while you learn the 'ropes'. At the end of that period, you and the employer choose whether working there at a higher rate of pay is an option. In addition, consider taking courses on line outside of the country, from the country where you want to live after this temporary expat location. Some degree requirements might organize studies, so that you only study on campus for a few weeks each year. Further, look at the skills you have, and see if you can offer to teach any of them, in exchange for a reduced tuition. Also take note that employees of educational institutions are often given options to take classes at a reduced tuition, no matter what grade of pay they are earning.
Spouses to husbands on foreign assignment often find themselves slipping into depression, or suffocated rage, at being stripped of the prestige of being an employed professional, while their husbands flit about on exciting new adventures themselves, and have less time for their wives.
If money isn't the primary cause of your desperation for work now, please say so. That would open up other avenues for solutions to your dilemma.
BTW: If the climate bothers you this winter, remember the Isles of Scilly have a tropical climate, and they are just a short flight off the southwest coast of England. You won't be leaving the country to go there. Making a trip there, even easier.
I would think that relocating to one's Venus line conjunct MC would be rewarding experience!
