I don't know what type of problem you had. I think that you already solved it, and got the necessary experience for work. It's a very tricky subject with this type of business. I own a small clothing shop in the city center. The First 3-4 years for me were the hardest of my life. I had a lot of problems to solve, but I overcame them. Now I own one of the best shops in my town. I can give you a little piece of advice. I use affinda.com, for sorting information. It works with your documents, CV-s, invoices, and searching for the necessary information you need. It's saving a lot of time.
