Thanks to everyone for replying. Please continue! It is good to know the views of people.
With regards to my business setup, it has come about through my girlfriends domestic cleaning company. She has had a few requests for carpet cleaning, which is the reason for me getting involved with carpet cleaning. I have seen a market out there.
At first, I am going to join her cleaning company and help out with her business, and do carpet cleaning part time. We are going to market the carpet cleaning through her company.
Also through my existing work, I have made contacts with letting agencies and builders so hopefully this is a line of work.
Through my girlfriends business, I have found leaflets not very positive, and the best way of marketing is through gum tree and word of mouth.
I had set my sights on dry cleaning but it appears I need to review this.
Thanks
