Welcome
I charge per opening and then ajust or add for other factors. If you break it down backwords it is really simular to figuring T&M+MU. That is if you took the time to figure the T+M+MU for each process.
Instead of asking how much per opening you really should ask help figuring your 1st year overhead and how many hours you will bill.
A mistake some make when starting out is to think they have almost no overhead (OH)and most of the company sales are income. Look back on past Biz threads and you may find all the cost of running a business listed.
Another mistake is to base your prices on the other shops. Worse then that is to try and be the lowest priced company.
You do need to figure how much you need to make per day, week, month.
You need to try to figure how much work you will have and how many hours you will bill per day on average. If your runing small calls all day half your time is running around, cleaning up, and collecting. If your starting out you may have many days with no work so the paying jobs need to cover this. Don't count on booking 8 hours a day every day of paid work. That is another mistake.
Don't believe the idea of get a phone number and a yellow page ad and you will have the phone rinning keeping you busy. In Chicagoland the phone books are loaded with companies. Last I counted was around 300 EC listed in just one book. I'm sure there are a number of micro EC that are not listed in the phone book. Also EC here will travel many miles for work. So how will you stand out and be found by the customer? Who will be your big customers? Do you have anything lined up?
One last note on pricing is you should adjust for the type of work. You did not say what you wanted to concintrate in. New res cookie cutter homes may be the lowest paying work. Custom Res better. Then Comercial new. Res service calls. Comercial service calls charge more. City work is an extra. Some reasons for this is the efficency factor of getting the work done, distance to truck, time to get paid, how big the job is (small costs more), emergency factor, and competition.
Try to take some time and read many of the past Biz threads.
Good luck
