Hi Andy,
Good to see you bounce back. You can make a go of this.
It will be hard to start, even if you have done it before. I might take 7-8 months, so good luck.
Go for a name that gives you an advantage snd remember the words window cleaner are more important that the name.
wishing you very good luck. Are you in the same area as before, were you are you wfp, do you have facilities garage etc?
