You might be able to hire an aerospace engineer from somewhere and give him the spec for the ramjet and say- go build. It would probably take a couple of years, but it's still probably cheaper than buying a turbojet- that's what? 10 man years worth?
Don't forget the rent on the combustion wind tunnel (a specialized type --
many wind tunnels can't tolerate engines running within them) he'll need
for testing it.
I don't know, why not just borrow a trashy, leaky, creaky, junked jet engine that just about runs, but is no longer flight worthy from somewhere. Point at ramjet. Do tests. It doesn't have to be a perfect test, just good enough that your flight testing has a reasonable chance of lighting and staying lit. Sell jet engine and make up a batch of cheapo ramjets for flight testing.
I don't want to talk about this anymore :-) I'm sure we can all see that a ramjet solution may well work, but may or may not be worth it dependent on a whole host of factors, including technical ones.
The biggest problem with this idea is that everyone will just go 'why not use a turbojet instead', and they would pretty much still do that even if they were standing next to a hot ramjet that just got back from a mission :-)
