one of my mates at work doesn't clean their car...
he asked me if i would be interested in giving it a good going over (after they had seen inside and outside of my car and wondered how i had managed to get it so clean

)
since they asked another person at work has asked too. I am more than willing to give them a good clean out (hoover etc) and wash but they say they want to pay me for it, i'm not opposed to earning some pennies but am unsure of how much to ask for... should i say a price or hourly rate... i'm kinda stuck..
any advice about what i should say?? a reasonable price.. etc??
thanks
