I would suggest the client first consult a CPA firm with expertise in
this area, as your client may not be affected by US sales taxes as much
as they may think.
For example, in the US the individual states aren't able to impose a
sales tax on goods shipped in from outside its borders unless the
shipper has what is called 'nexus', or a physical presence, in the
state, e.g. an office or the regular presence of sales or service
personnel. (It is the buyer's responsibility to self-assess a 'use
tax'). Although some states are trying to make an exception on catalog
sales, these attempts have been halted at the Supreme Court level while
others are still in the courts. 
Anyway, some expert advice in this area would be a good precaution.
