US Citizen with UK apprenticeship

It seems nearly impossible to get a visa for work from an unsponsored employer. I have an apprenticeship with a woodworker who is the originator and one of 3 people in the world making a specialized musical instrument. Does ANYONE have information on how I can get sponsorship or a visa, or is the only solution for him to become a sponsor. He was planning on paying me, and I have a place to stay with his ex-wife, so I can basically work for food and rent if I have to to make it possible, I will also be moving with my 3 year old and girlfriend, and will need to stay for atlas 1 year.

ANY HELP WOULD BE AMAZING! THANKS

Not aware of any viable options really.
My understanding is, even if employer became a sponsor, the post would have to be offered to UK & EU candidates first.
