I have loads of questions and will probably forget half of them but i would really appreciate wisdom from anyone who has experience of this kind of business and consensus on whether i can/should do it?
I have been a cleaner through an agency for 3 years. I love doing it and have been talking myself out of setting up on my own for as long as i can remember. Through the agency the work has been very part time and so recently i took another PT job in a shop which has just driven home the fact that all i really want to do is work for myself as a cleaner. It is actually quite sad and depressing that i daydream about cleaning when i'm in the shop 
So, i need to make a decision. Do i go for it? I am worried about not getting enough business to survive.
I also have no idea what i would need to do legally, other than get public liability insurance and register as self employed.
It is my intention to start out as a cleaner but i have thought of extending to things like laundry/ironing, changing pet bedding, dog walking/feeding, pet sitting etc. should I offer these services straight away or wait to see if there is a demand? I'm thinking just offer? Are there any services i could offer that i havent thought of?
Another worry is that i am a lone parent and have no evening childcare, at least not until i am earning enough to pay for it. I have daytime childcare but am i likely to have lots of work in the evening that i would have to turn down? Or could i employ someone to do the work i couldnt do? That sounds like a scary idea to me but i suppose lots of people do it.
Any advice or wisdom greatly appreciated.
