You need a new lawyer.
Credit cards are the safest way going. I've been selling online for nearly a decade and can count the "attempted" chargebacks on my fingers. I say attempted because most turn out to be they just don't recognize your company name when the bill comes.
Of course, it does matter who you are selling to, and where you are selling. If you are selling on eBay you must have PayPal.
A US merchant account will not do you any good outside North America. You will need WorldPay or MoneyBookers, etc. for the UK or EU.
You don't say what you are selling, or an average sale amount. That makes a huge difference when talking about TT instead of plastic.
