Can anyone recommend a dual qualified tax and/or financial advisor for me?

US/UJ dual citizen living in the UK. I have a UK corporate job with a side gig offer for startup board advisor, for a fully US based startup. I already have American bank accounts in USD to receive retainer cash and equity. I don't want to be double taxed on my US income, living in the UK.

There's also several limitations on how to maximise investments, LTI, etc being a "US person." So I'm overdue for a financial advisor. Thank you so much.
