Tax Returns

I need help with my mother in laws tax returns. I have done tax returns for myself so have basic knowledge. But I need to go over about 8 years of tax and don't have any record apart from bank statements. She also bought shares made/lost money not sure how to fill this in correctly. So I need someone who really knows what they are doing to help me out. Thanks, Marieke.
