Congrats on incorporation - nice first step. This business stuff is not as complicated as you think at the beginning of your venture. Remember, people like you have been doing this in America for a very long time and before America even longer.
In a one-person business like yours, if you are not comfortable with the paperwork like taxes and payroll, etc. - farm it out to someone who does this for a living. There are many, many small firms - many like you, one-person operations - that their job is to provide professional accounting and paperwork assistance. Find one and make them your friend. Then ... get on with the work at hand - selling and providing your services and growing your business.
It sounds as if your advocation is now your vocation and honestly, it does not get any better than that - doing something you love. Don`t let the details of paperwork stand in your way. Yes, you have to pay attention to these details and a good accountant (maybe even a virtual assistant) will help you do this. Do what you do well and hire others to handle what you can not.
Don`t be afraid - get that out of your mind. Have definiteness of purpose. No fear. Build your "mastermind" group and support team. When you`re a one-person show, you create your own team of support actors to help you become a successful business person. You can do it.
Don`t fret. It will work out. 1st rule. all the legal mumbo jumbo doesn`t matter if the business isn`t bringing in money. Make sure you have covered the basic steps first.
Got those steps already? Cool. Then as far as the legal stuff, I personally recommend:
Good luck! Let me know if I can help further!
