Rather than reach for the US why not try france or spain (or the UK)
-- common currency (except for the uk)
-- Fewer time zone issues (out of band support and troubleshooting)
-- Not having to deal with US taxes (as in sales tax vs vat)
-- Gives you a chance to work out I18N l16n in a smaller pool/area
-- is your client base one that would help you out if you put up an affiliate model? "sign up french clients and your next month is free"
If your looking for "marketing partners", are you looking at folks who would fit in a "basket of products" related to what you do? If you sell razors who sells shaving cream, can you team up with someone who is local to do the CS and sales for you hear, and you do the same thing for them there?
