i wouldnt do it for free i would soon realise what allot of effort for a potential customers, when you can pick them up easy enough without doing it free. Today i went to do a new customer who contacted me through my website, this was only a £13 pound one as it wasnt very big, then she said next door might want theirs done too, so i went over and got that one too at £15. I then flyered the whole road. People are willing too pay, if you do a good job ive found, and for some of them whatever you would have charged would have been fine, after doing these two today i realise i could have done the second one for £25 maybe.
Ive got a few underpriced ones, but i still do them anyway, and just try and pick up more work and go for the bigger prices, they can only say no or yes and if not then go to somewhere else.
By some of the prices ive seen others on here charge, all of my properties are underpriced, so im aiming for the better ones.
