I'm about your age and started my own business 2 years ago. I am extremely blessed to be in a part of the country that has not been too hard hit economically, so that is a MAJOR difference in our situations, obviously. Here follow some things I was/wish I was told when starting a business...
1. Follow the money. You should absolutely be in this for the money. When you are "just starting out" is when you can least afford to be paid less than you're worth. Be respectful but firm in pricing.
2. You are recently registered. As someone else has said, this means the state considers your "minimally qualified" to work independently as a land surveyor. Triple-check everything. Challenge your assumptions. Take a minute and think of the arguments for the prosecution and defense if any aspect of your project would be litigated. Did you win?
3. Cashflow problems can hardly be over-stated. If you're fortunate, in your first year or two you will find someone to work with you who can wait to get paid until you do. I was fortunate. Sort this out beforehand. If you land a $50,000 construction surveying job, can you front, say, $25,000 in payroll before you get paid?
4. Pay your employee more than he is worth. Don't be stingy.
5. You better be doing high level work. Charge accordingly.
6. Finance good, late model (if not new) equipment.
7. Maintain good insurance at at least the minimum requirements of the projects you hope to handle.
8. Reputation, reputation, reputation. Go the extra mile. Always always be on time. If unforseen circumstances affecting budget or schedule arise, call your client IMMEDIATELY. Rule of thumb: if you wonder if you should make a call, you DEFINITELY should make a phone call.
8b.Provide awesome service. Do your best to be on your client's team. Work till 10pm so that concrete pour happens on time in the morning. Draft till midnight to deliver that drawing at 8am so the real estate closing happens at noon.
