Ask HN: Recommendations for UK accountant familiar with US tax law?

A bit of a reach, but I figure maybe someone on HN might be in a similar position. I’m a US citizen living in the UK on a 5 year visa. I do software consulting for US clients and bill the through my US corporation, while doing the actual work sitting at a desk in the UK. I need to talk to a UK accountant who is familiar with the intricacies of both the US and UK tax systems. If anyone has been in a similar position and found a good accountant, I would appreciate a reference or introduction. Would also be curious to hear other’s experience in this situation, but ultimately I need to talk to a professional.
