I'm afraid I don't have much input on your questions since I'm not there yet.

Since it appears you've had quite some success getting leads I'd like to ask you a few questions regarding your last HN post:

1) Did ariba work out for you ? If not how did you get the opportunity to bid on large company RFP's ?

2) What did you have to do to demonstrate that you were a credible supplier for these clients ? You mentioned having done work as a subcontractor. How were you able to valorize that work as representative of your own capabilities ? Were these publicly visible projects, even if your name wasn't on them ?

3) Did you have to jump through a lot of administrative hoops to be considered - ie. DUNS, business insurance requirements, etc. ?
