Accountant

I have a full time job and looking to do extra work on weekends to support the wife in full time education and three kids. I listed myself as a limited company, started a business account but need someone to work out the intricacies of ensuring the tax man takes as little as possible. I aim to make 10 to 20 thousand a year from these extra jobs but hope someone can work out salaries for my secretary and extra expenses which I can claim.
