Massage related question

[percival]

I'm about to wind up my massage business. My existing insurance and registration, which cost me 100 pounds per year (about 70 dollars), are up for renewal in late August. I intend to keep giving people massages, but as barter for e.g. childcare. My question is: if you were getting a massage as an exchange for another good, would you prefer the person who gives you the massage to be insured, or would it be enough to know that the person is trained?

I'm asking because in order to "recoup" the outlay, I would need to give 4-5 massages in exchange for 10-15 hours of out of hours child care.
