Bartering and swapping

I was getting my hair cut earlier, and we were discussing the hairdresser's holiday plans.  She mentioned that to get to her holiday location, she needed another vehicle, ideally a people-carrier to fit six people.  Apparently, in August, at school-holiday time, hiring a people carrier costs a massive £400 for a week!  We discussed whether she could borrow one from someone, and we thought it would be great if she could barter for it, maybe offering some free haircuts plus use of her small car, in exchange for the use of their large car for a week.  I guess such an arrangement would only work in a fairly small community - you would want to either know the other party, or know a friend of theirs - as it would involve quite a bit of trust.  But it would be great if such an arrangement could work.  I think I might ask the person who runs the local oil-buying group - which we have now joined - if he knows of any bartering groups in my area.  If not, maybe we could set something up.   In the meantime, the hairdresser is going to sound people out via Facebook.

Anyone else have any experience of bartering, and if so, how did it work out??
