Travnet,
Having visited FTE in Jerez, I can confirm they can help with the loan. They have an arrangement with a bank, or you could choose to go to HSBC. If you pass FTE's test, they will supply you with an offer letter. This letter is used to help get the loan.
I'm sure FTE would let you change dates if you cannot make it on Friday. Though it would help if you could arrange it with someone yourself to swap dates. I'm on Tuesday, is that any good for you?
Regards,
Niraj.
