Use a non-standard WO to estimate material and labor costs without actually incurring the costs?

Summary:

Client would like to use a work order to estimate the duration, material costs and labor costs of a quote—they don't need to actually perform transactions, but I am not sure how they would be able to view costs without performing the transactions.

Is there a way for them to be able to view the simulated cost of the work order once they assign material and resources to the operation, but without actually incurring the costs?
