Welcome, but hope you get a lesson real quick if you do all your work for $30.
There have been many that tried that, but the first time your work truck breaks down, when gas prices soar to $5 a gallon, hope your pricing structure survives that.
I haven't been in business surviving and thriving because I will advertise any lawn for $30... A lot of people who have pulled that stunt, well they're no longer around.
Be honest with yourself, would you want to make a 100 per hour or 100 every half hour......don't make money with a fixed rate unless you pic and choose.
Anyways, good luck and may you learn quickly. There's a reason you don't post your price per cut or monthly charge.
