So provide a conservative estimate billed in week-long increments. You come in way under the wire, they get a week or two deducted from the final cost of the project. Customer dicks around with requirements, you get to say "I am happy to do whatever you'd like and make whatever changes you'd like but I need to remind you that we have a fixed schedule for this project".
All this stuff about "what's best for the customer" tends to be an elaborate justification for complicated pricing schemes that alienate customers while ironically undercharging them for the services you provide.
Avoid customers for whom a week's worth of your time is a make- or- break- the- business decision.
