o... k.... then... offering mates rates is all well and good, however if you're going to do it, make sure to provide the details... i have them in my van, with the usual deals (which i put on my dash at jobs:P)... might make it a bit less iffy... and post around make sure people get to know you first?
There are plenty more engineers on the site which can provide mates rates and be trusted
btw... new customer deals are currently better IMO...
