Look in the Yellow Pages
Send everyone a 22-page RFP (a Word document, prolly)
Wait for responses
Pick a winner.
Option 2 (after you’ve lost patience with option 1, cos it’s rubbish):
Seed the networks with a hyper-abbreviated graphical invitation to tender.
Blog about it.
Email all your mates (including Sam’s UKNM, natch).
Twitter a bit.
See what happens…
