How hard to start???

I read a lot on internet how the gutter cleaning companies are working and which tools they are using and what is really worth to invest. Well, I made some general mistakes like everyone. I bought a gutter vacuum system for 600£, a camera system around 120£ generator for 400£. That was totally useless at this point because for the next 3 months I go 1 job!!!!!
I sold it straight away.  Might be next year I need another one but that point definately doesn't worth to keep. No customers, no effective marketing.
