If I were you I would not restrict myself to just tiling. Maybe learn how to lay all different types of flooring as well as tiling. If you can install wetrooms then that is a big plus, especially if you can tank them in vinyl - that opens up doors to commercial work, like hospitals, care homes etc. But also lay homogenous PVC, (real) linoleum (very specialised, used in all schools here, and many council office buildings), safety flooring (Altro etc), Amtico/vinyl floor tiles etc (popular in shops, banks etc).
Substrate prep is key for those materials (paid on a time and materials basis) and you'd be surprised that you might be able to charge as much per m2 to lay some of those materials as you can to lay tiles. You will be able to lay
at least double the area in those other materials than you can
tile. I and another chap laid 136m2 of linoleum on Friday in a school library. They pay 350kr per m2. So that's just under £4.5k for a day's work for 2 blokes (and that was an 8 hour day, including half an hour driving each way, so 7 hours actual work. £320 an hour, each :hurray
. O.K., that's not every day, but has anyone made £320 an hour tiling? I haven't. Lucky to get that a day!
My advice is whatever you do, make sure you do it very, very well. You won't make any money as a Jack of All Trades, Master of None, but having more than one trade means you have more options, and to be honest, tiling is a damn site harder, and more physical, to do well than laying a lot of other types of flooring. I could have laid that linoleum job on my own, in the same time, but the rolls weighed 206kg each, so I couldn't lift them on my own, not even onto the special trolley we use.
Good luck!
p.s. Don't all start resenting me for making £320 an hour on Friday. By the time the Swedish government has robbed of all the tax it will be about 3 quid an hour net... :incazzato:
