Pitch the gig, sign the contract, then you do the boring logistical details. One of them is arranging travel. At my shop that was simple: "How doed $FOO handle business travel? Are you going to book my tickets/hotel or would you prefer to be invoiced for them?" "Great; send me a copy of your travel policy."

I also thought, early in my consulting career, this would be a big deal. It never was. Nobody who can hire 10 programmers is surprised what a trip from Nagoya to SF or NYC or Berlin costs.
