hey i am in the exact same situation... I called orlando flight training in the us who do part of the conversions...
www.flyoft.com seemed pretty nice but it is pretty expensive it seems like. Expect 8 hrs of flight in the USA the writtens, but to get your IR you need he said about 15-20hrs on avg then u need to complete the mcc training. The kicker is i need a caa class 1 to start which means i have to goto Europe to do that. Not sure what to do if anyone has some suggestions that would be great...
3400 usd for the written
10500usd for the ir conversion to be completed in the UK
4000usd for the mcc... to be completed in the UK
Not sure if these prices are good or bad still researching it.
