Ordering fro Bob Roberts goes like this:
1) Find what you want on his site
2) Email the order to him stating both the part and amount. You can just copy and paste from the site.include your shipping info. His email is listed on the site.
3) He will then send you an email with the full cost including shipping. My bet is it won't be cheap. you may want to first tell him you want to get the cost before you commit.
4) You send your payment, once he gets it, he sends your stuff.
Theres an ordering faq on his site with all the info.
I'm guessing this may not be best bet for you. The first time ordering with Bob can kinda suck because of the waiting for payment and all that. He will not accept paypal.
For me, I love ordering from Bob, he cross ships my orders so I always get my order in 2 days even if he hasn't received my payment yet and he never screws up my order. But he won't do that on your first order and I'm not sure if he'll do that on out of country orders.
