Apart from the usual suspects....HSBC, CDL, parents, lottery (sorry LOTTO!) I have been looking into VirginOne account - it only really works if you've got a mortgage, but the flexibility it offers seems really good.
Basically it lumps all of your loans, credit cards, mortage, bank account into the same pot. As you pay of the debts, that money becomes available again as your 'borrowing facility' - in addition, as your house goes up in value, you can also borrow against that without having to re-mortgage.
i hope I've explained it right!!
Aircart - it might be useful to others also, but could you give an overview of the presentation you gave to HSBC to secure your loan i.e how did you sell it to them, do you have mortgage, is it all secured or part secured etc
