Def go the personal loan route..
Pretty sure Ianh20 had a post few weeks back about asking his account manager for a business loan, but got rejected cause they didn't have fund to lend, but would lend money for holiday, car etc.. Crazy really!!
Got a loan few years back with Halifax had money in my account by end of the week!!
MIght be worth trying your current back can imagine will save a lot of hassle credit checks etc..
