What business arrangement/relationship is best for us?

My small unfunded start-up innovation company, N.F, wants to promote/develop, directly or through strategic partner(s), an independent Polish inventor's technology IP We need to start talks reg which business arrangement/relationship can be formed. Which is best for N.F.? What is the typical value position [reward/compensation] each can expect? We invited a strategic partner, Ricardo, to the funding opportunity with the Navy and we are providing the IP, some of which is patented, pending but most is unsecured. Ricardo will do the R&D and be paid from the Navy grant with N.F. playing a minor/advisory role. What might Ricardo Engineering want in this venture? What is the typical value position the strategic partner will expect?
