It may depend on what is accepted and what your competition is doing, market areas are different. Some will include all costs even supplies in their hourly rate and some will charge separately for them.

You probably have a good sense of how long it takes to do the work, use these skills for pricing. Remember that all of us would like to charge more but it is always a competitive market Ccleans; don't over charge and do not under charge.

Remember that you have three days to complete this job, do you have help?

Is this job being bid by other companies?

Also it is important to have a walk through inspection with the client when you are finished so they agree that it was done properly. Much more difficult for them to come back later to say there are problems.

One way is to always find time to talk with the decision maker, get to know them and bounce some figures off them to give you a better idea of what to charge.

Bidding is a learning process. If you win great if you lose learn from it for the next time.
