Trevman,
The advice of talking with possible GC and owners is real important; if you don't get carried away the volunteering is also very good.
Two things that are very important is that you bid your work accurately. Do you have a good handle on your labor burden costs for employees? Don't wait to get them you should (in my opinion) be bidding as if you already have employees and allow for them in your bids. Do you know your overhead percentage accurately? Overhead at best is a guess and needs to be reviewed periodically, 3 to 4 times a year.
Estimating software is if used correctly very useful, if you use it incorrectly then it can be a disaster. When you get to that point demo lots of different systems to see which works best for you. Expensive does not always mean the best, but if the cheaper one does not do what you want then it is also a waste.
Don't be in a rush to get large, yes you need to pay the bills, but getting larger then you can handle could lead to bankruptcy. Use your slack time to organize, plan and learn. Do you have a written business plan? They are not as hard as some people make them out to be.
Seeing as your relatively new one item that you can easily implement is to track both your material cost and labor hours for the projects you do have. This may be a shocking experience. I rather learn on a small job then a large one.
Here is an Oxymoron for you, be aggressive yet patience
