Aqua, most of my new leads used to come from tile shops where im 'one of their tilers'.
They hand out your cards when a punter buys tiles from your area and asks for a decent tiler. You in turn send your own punters there to get tiles and they give them an extra discount. You can get involved yourself and go with the punter and skim off some of the discount yourself. Alot of guys do this as its ££ in before lifting a trowel. You do have to have decent cash flow and can turn over alot more money putting you inline with the VAT man.
Ive asked my tile shops not to hand my cards out anymore. Your always out pricing work and its pretty cut throat at the minute. I dont need all the cold pricing, so I dont do it. Remember most folk get 3 prices so you should only win 1/3 of your quotes if they pick on price alone or your too cheep. Remember as well an experienced tiler will be quicker, ha might well do a bathroom in half your time. So if you think you need £200 a day to do quality work, the experienced chap needs the same, guess whos quote will seem expensive based on dayrate alone. You may well ahve to price on m2 to get a feel for how many jobs you win. Convert each job into a dayrate at the end and see how you are getting along speed wise.
Vary estimates as well based on how busy you are. ie if you have nothing on then is it better to earn 100 a day or stay at home, only you can answer that! But if you are booked out for a few months you can up your prices accordingly. You do get a few.
One bit of advice i was given, keep a diary and stick to it. If you give a date and time then be there. Nothing worse than a punter waiting around for a trades man to call...
One last thing, make friends in the business, tile retailers, bathroom fitters, plumbers, sparkys, builders...your best friend though is word of mouth, it takes time to get known but it does happen, then people call you wanting you to do the job..
Good luck
