But given that the opportunity is looking for proposals in the field of communications and propulsion, it sounds like a good chance to team up with one of the university groups who are working on miniature Ion engines. They are about 3 inches across and use as little as 36W. A 3U cube could house one of those and you could target orbital transfer and space qualification as the objective. The engine part could be project managed while the comms and structure could be taken on within AMSAT.

Thanks

Some of the orbits are very short lifetime but there are some useful ones there:
