I did the same as you want to do some years back.
It is a very cool way to do it. He found a bike for me and registered it for me. So I could just fly in and drive off (after

Use advrider.com instead of the HUBB. advrider.com is mainly americans where the HUBB is very mixed.
Make a cool and fun "application" there and I am sure there will be lots of people willing to help you. You will need to take a leap of faith though, since you will be transferring money to someone you don't know to buy something you haven't seen.
I did it and I am sure you can do the same.
