Im based in Glasgow, and im finding that work is sporadic, to say the least. But then again, i work outside and most of my work comes in the summertime.. or leading up to the summer time.. The general cleaning industry is year round, which is great for you.
As for experience, well it sounds like you have experience of cleaning, just no experience of actually running a business. I was exactly the same, as was probably everyone on this site at some stage.
The trick for me was, be confident. Confident in your abilities and confident of yourself. Customers are like sharks, they can smell a wounded animal..lol
If you think you can clean a house to a good enough standard to get paid for it, then i say go for it, flyers, advertise, tell all your friends, and their friends, as pristine sais, MARKETING...get out there and do as much as you can, and aslong as you stay confdent, ppl will trust in your abilities..
