I'm going to start building a rate book. I have looked through alot of the archives here and have some more questions about how some of you guys do it.

What level of detail do you take your line items to?

I see some of you have a $XX.XX price for 1st item and then less for additional.

What kinds of things do you have adders for?

Here's a sample job, how would you assemble a price for it?

Single family ranch with an unfinished basement. Owner wants a 30-amp 240-volt electric dryer and 20-amp 120-volt washer circuit in bedroom closet 40' away on the first floor. FP stablock panel in the basement with room for breakers. EMT required. Dryer needs 4-wire cord.

To what level of detail would you break that job down to?
