If you are good at the duties of running a machine shop but not good at paperwork than obviously you need either a part time secretary, an accountant, or both. Don't hire just any accountant; I have been surprised to even see jealous family members take advantage of a person your age in business. The only person who should know your profit margins in business is you. And your accountant, if you should choose to use one. If you try to do paperwork and office duty yourself, you will find it is taking away too much from the work you actually enjoy doing. A real boss learns the phrase 'delegate responsibility to a subordinate' but never actually says it out loud at work. You cant delegate anything unless you hire a few employees; look at every 90 day period quarterly to know what seasons you can expect less work in advance. The '1st quarter' Jan / Feb is usually the worst 2 months of the year to do business on. It's always good to have a lawyer on deck because taxes are very confusing and everyone makes mistakes! Obviously it is hard to see a lawsuit coming even if you are conducting legitimate business and the other party is exaggerating. People will try to take advantage of anyone in their 20's beginning business. It's not a matter of if but when. You might be shocked to see some people develop a relationship with you for years before making their move. Some wolves dress nicer than others.
