1. 80 GBP
2. no, but there is a spread between the rates, so you can call hsbc to ask them when is the best time to do a wire.
3. not that i recall. copy of a bank statement, you also needed to deposit 5k GBP which is roughly $10k. you can start the registration process online, and it will show you all the information you will need to provide them.
they asked why i wanted the account. i said i do business with foreign companies. they emailed and asked which companies and where are they located. i said pay tech international and gibraltar. that was that.
most of this stuff can be found on their website, or calling them. they are very helpful.
