You don't really fit any pattern for a suitable visa.

Ideas that you may be able to fit into with a little squeezing include:

L1a -- open a branch office of the UK business in the US and transfer yourself over. There are guidelines for turnover and employees -- and the latter you are definitely light on. Also, the US business would be expected to produce and employ. Major advantage of this method is it can lead to a coveted green card.

EB5 -- sink an investment of 0.5M USD in a suitable project and you get green cards. This route is due to end in the fall unless Congress renews it.

E2 -- the last hope method! Sink 200k USD or more in a US business and you can live here as long as the business is viable, but there is no path to a green card. Kids must leave at 21 or find their own visa. The shores of Florida are ravaged by the flotsam of this particular visa .

In all cases, you need an experienced US immigration attorney with a proven track record to guide you. It is quite possible to retain the services of a US-based one and communicate by phone/fax/email.

I would not recommend asking for advice from your local US Consulate. They push the pieces of paper around (rather slowly IMO)......but that's about it.
