True I've probably been watching to much YouTube vids on window cleaning and what set ups they have.One of the local window cleaners started with a Pure Freedom trolley, an open trailer that carries 15 x 20 litre drums of pure water and now the family Mondeo he puts his pole and cleaning stuff in.
He has run that same trailer for more than 10 years although the Mondeo is now only used for work.
Originally he began working out of the back of a Citroen Picasso.
I agree with the comment made by @Iron Giant. Some people aren't cut out to be self employed.
I certainly wouldn't spend big on a system until I got a round established. It requires a lot of hard graft to achieve this. It will be even harder doing it over weekends when you are tired from working a normal 9 to 5 job.
Self employment has it's perks but also has it's downside. No sick pay or holiday pay are two and if the weather is really bad like it was 10 years ago, we had very little income coming in for 6 weeks.
We do have a little more security in that we work an established round of customers with repeat work, unlike say roofers who have to continually advertise for work.
I wish you all the best in moving in our industry.
They guy that used to do my windows has a backpack on a trolly and some 25lts drums in the back of his van and has done it this way for years..
I will probably do it this way until I start until business picks up.
