Falcone,
I noticed in 1 of your earlier replies, that you are currently working full time.
I recently had a mate who wanted all sorts done for pennies and although i was after the experience and the money, I thought
1. Would it be worth the aggro having his mrs's hovering around bitching about every little thing i done and,
2. Then working my nuts for pennies only to end up being branded "cheap".
So i found it far more satisfying just to tell them that i was far to busy and they should try to get another tiler, because as usual most customers want you to have started yesterday and its a great feeling when they ring you a few weeks later to say they cant get anyone and funny old thing - Your price has gone up a couple of extra quid, If they dont contact you back, there is every chance the old man has done it, so they will still call you at some point to do a repair job.
Honestly - Stick with it, because they need you more than you need them.:yes:
