Any tips on the approach got flyers/ business cards am i missing any thing??
A small ad in the herald for the next few months would defo help.
As for other advice,..
Don't underprice just to get work,.. you'll regret it very quickly and get a bad rep when you start doubling prices on your 3rd clean!
Go WFP from the very start if you can. A backpack setup can be very cheap, add a DIY pole or 2 and you're laughing.
Organisation is key,.. know EXACTLY what your round is, when each job is due, what you're making per hour in each area etc,... this knowledge will help you identify the weak spots in your round and fix them quick. Defo get WCpro or George,... it'll pay for itself in a mater of weeks.
Market on the go,.. if you get 2 or 3 houses in an estate, every time you clean them drop a flyer in all the neighbours doors.
Make friends with other local cleaners,... their advice and help can be invaluable, and they might even throw some work your way.
