well youve been bowled over with replies here mate, but i have to agree with q-plumb, i think youve gone for the cheap market! - solution- Treble youre price, and convince your customer it will be a trouble free installation, give them peace of mind, and confidence in you.....it seriously works, even if you take your qualifications and insurance certificates with you,and a portfolio of work completed/ photographs with you, when you initially visit the job, and offer a guaruntee of workmanship/and callback service, in the unlikely event of any problem......what more can you do, than offer the full packge?...people dont mind paying for quality but are wary of plumbers and other trades, and dont want to be had - over, once youve given them confidence in you, theyll refer you to mates and use you all the time.....dont plumb for cheap mate, its hard work - good luck, let us know how you get on - cheers moore
