Two big questions for the beginner; is there a market for a guy with limited equipment and experience? But, ok, let's say you rent in the beginning, the owner will probably move it for you (but, if you own it you have a whole different set of issues). To make it easier let's say you rent it. Now, if you actually get work and can get the equipment there on time with the right buckets, full of fuel and it doesn't leak - now, can you do the work?
Seriously! Everyone on a jobsite will tell you they know how to operate a backhoe, but starting it up isn't operating it. It takes experience to know how to set-up and start a dig and where you'll finish it; to dig to grade or keep your trenches straight, clean and the right depth; how to jump ditches; work around others; not ruin others work; how to "feel" your work or recognize warning signs that problems are close; etc.. I could go on but the real question is, can you do the work? Sure, experience is slow coming but once you have it you are marketable, BUT, what will you tear up, ruin, or who will you **** off until you're competent? **** off enough subs and you may not be around long. Now, you did the job and you want paid. In California we have lien rights but you need to be a contractor if you charge over $500 labor AND materials, are you a contractor in your state? Anyway, you bill (invoice) your sub and if nothing goes wrong or is held up you MAY get paid in 30-60 days. Can you wait that long because sometimes it's even longer and your operating costs need paid, can you hold out? Now, as a contractor, you are self-employed and your pay won't have any withholdings, that's all up to you, are you responsible enough to save enough to pay your taxes. Ok, I'm not trying to scare anyone but all this and a lot more will make your business a lot larger than sitting in the seat of a piece of equipment. I only did commercial work and stayed away from residential. Today there isn't much commercial work out there. I retired but some of the best operators I know are having a tough time of it right now and it may not get better for a long time. Do what you're doing right now, ask questions. Go spot for an operator and see what's actually involved, it'll be boring but you'll learn a lot if you pay attention and ask questions. Good luck. Oh, I've got a semi and a 35 ton lowboy left if you really want to jump in, but you'll need a Class A license first, do you have one? Wait until you deal with that end of the business.
