web portal for UK/USA based USA immigration solicitors?

[hmmog]

Hello

I own a UK business with clients in the USA. I need to spend a few years in the USA building the business (with my family). I have cash to invest which hopefully should satisfy the 'investor' visa requriements.

I am getting nowhere fast with the UK based USA embassies etc. It seems like there are massive waiting times for interview.

Have been searching the net and yellow pages etc. for a GOOD law firm that could manage the process for me.

Can anyone make a recommendation or point me to a decent resource with a listing of law firms?

Thanks
James
