Profit in your first month? i didn't get a profit for about a year!! It took me almost 6 years of serious hard graft and marketing myself to reach a point where i'm at now.... has paid off though cos i never ever worry about finding work, am booked solid for the next 8 weeks and have jobs confirmed (but with no start dates) right up until December. Get in the tile shops and build a friendship with them and be sure to give them a generous drink if you get a job from them. Pick the phone up and call every single plumber in your area and be honest about yourself and your experience and if you get a job from one, turn up, do a good job and keep there customer happy.... plumbers are always struggling to find a tiler they can trust, and of course give them a drink (and be generous, without making yourself skint though).
I have four plumbers who only use me and if i aint available they make there customers wait or they tell them to source another tiler themselves. Me and one other tiler are also the two highest recommended tilers in a big tile centre which provides me with a ton of work but again i give them a nice drink. Oh yeah and the other tiler, i called him up and we now swap work with each other or pass work over and generally help each other out where we can.... so important to get on well with other trades.
I am not trying to brag with this post mate and if you look back at some of my posts from years ago you will see i was seriously struggling, but with a hell of a lot of hard (like i said 6 years) work and determination and time spent learning i am now in a position where i have so many people i can call for work and my phone rings a dozen times a day from referals, old customers, plumbers, chippy's, builders, tile shops, other tilers that i am now one of them tilers that i used to envy so much........... stick with it mate and it will pay off for you.
Good luck
