Right off the bat, I would have to say "Good Luck" in locating 100 warm bodies to work at your local facility. The cost of the facility, workstations, etc would seem to me to be incredibly huge, even if you were able to find the bodies to fill the chairs. Conducting training classes for that many college students (all at entry level) would likewise be a huge overhead expense. But then, perhaps your funding is coming from a bottomless well. Something few of us enjoy. I would estimate a $40K to $60K per student training expense for the first year. If you were in competition for the project you mention, that expense would likely shut you out of the opportunity.

In San Antonio, Texas, we have had the task of networking just about all the VFP developers we can find just to subtlly wage war on wages, and are making quiite a bit of progress in this area. We enjoy a much lower cost of living than, say Austin (just 80 miles up the road)

The last body we found to fill a programmer position was after the opening existed for around 9 months, and we ended up finding a recent graduate from Texas A&M, (Major MIS) and training him from the ground up. We were not disappointed with his progress, but at the lack of contracts we can bid on due to the lack of journeyman programmer types that will work on site, as well as satisfy citizenship requirements for Government security clearances.
All of our projects to date have been onsite, and all of our development staff are full time employed with benefits. We have never had a layoff.

To even think about trying to hire 100 bodies for an onsite project would give me major migraine, I think.

But, should your project not have high security requirements, you might consider breaking the project up into multiple small projects and outsource that to developers, maybe even some moonlighters. Placing it on the web is going to require a scripting front end, such as Allaire's ColdFusion, or Westwind, and that is entirely a separate area of expertise, and can be a little tricky to get the functionality you expect from a VFP application. Web enabling databases is where it is going, it seems, and the scripting programs don't care what brand of back end database it is dealing with as long as it is accessable via SQL.

You could facilitate partial outsourcing by first developing a concise, well written software design document. Your programmers could code from that document and upload their code segments for testing, acceptance and payment.

This ought to get some comment.
