Jobs/work

I'm new here and posted in introductions yesterday for help.

Also work. When I'm better then I am at the moment would really like to go back to doing pet care, dog walking, holiday care, that sort of thing, also some gardening if my back condition allows. 

I do not work well with other people. It just does not work out. I am very solitary. 

The pet and garden business didnt work out well previously and I have financial difficulties.

What jobs do people here do? What jobs can anybody recommend.
