DOUBLE IT. Always double your initial estimate of engineering time.

ADD ANOTHER 3 WEEKS

ADD THE FULL COST OF THESE ITEMS. EAGLE COSTS MORE THAN THAT.


Add an hour or two for billing the client, add the time you spent making the
proposal, add four  hours or more for ordering parts, add 5% to 10% markup
on parts, add shipping on parts, and time to pay yourself to be your own
accountant.  Maybe you don't bill your time for accounting, billing, and
ordering parts at the full rate, or maybe you do.   Proposal time should be
at full rate.

No Joke. These suggestions are serious as a heart attack.
