Hi, I am questioning whether I should officially go part time self employed selling on Ebay. I do make this a full time hobby and I would like to move to self employment. I have a disability, a single mum with children under 6 years old. Do you know whether I could go self employed doing this and would I qualify for working tax credits. Do I need to make a certain amount of money a month to qualify for this? I would be grateful if anyone could help me with this, thank you.
