Yes I do both , just make sure you get a good machine like a ninja ( full set up about £2500 new ) and do the course , its easy , most of the things are comman sense !
you will have to advetise in yellow pages or leaflet drop if you want to make any good money tho' which can cost a bit .
I find the work comes all or nothing , one min you keep looking at the phone to see if its working , next min you cant keep it in your pocket for calls - most of the time when you have the 50ft pole out in a strong wind !!!
You will look at the diary on a monday and say '' not much in this week - easy week on the windows
'' next thing the phone will go a few times and you rushing round like a loon working eve's and sat's trying to get it all done
you can make more money than windows if you book your jobs in right .
