Can anyone recommend an ideal co / m&A firm / resource to approach re exit strategy. We're a v fast growing start-up, but want to assess options. Thx!

UK based market-place scale-up with strong global / US presence, 4 yrs old, bootstrapped, annualised turnover rapidly approaching £2m pa, growing fast, huge global scope and coverage already in growing market. Strong team, partnerships, very positive global PR, growing market and market leader disrupting very attractive consumer sector, award winning business, capital efficient, fantastically rewarding profitable business, top 40,000 Alexa rating, just want to assess options (due to personal circumstances) and consider strategy for the end game - not necessarily there at this stage, but want to know how best to work towards exit and glean the best advice to optimise options for that. Also whether that would be best targeted in UK or US. Any pointers would be very much appreciated.
