Nighthawk, from other threads you have posted I see that you and the others of your group have actual working displays, though I cannot remember if you do tooling in them. I think that with customers/benefactors actually seeing people at work, making the the same/similiar items that they are obtaining, gives them that extra urge to part with the readies.

I think the designs are outstanding and in this day and age a most appropiate accoutrement. I also think that the cost you propose is most reasonable.
All the best for the project.
