At least around here, if you plant switchgrass you're better off not paying for the other species. Without a bit of maintenance; strip disking or burning; you'll end up with all switchgrass anyway. I'd also not shy away from adding a forb component, especially some legumes. Helps the grass and is great for the critters.
Though there is a bit of red tape involved and some restrictions on management, I'd not discount enrolling the seeded portions into CRP/CREP if it qualifies. Rental payments might not be much, but would be better than nothing and they will help with installation plans/costs. If you don't want the burden of a longer term contract look and see what they offer through EQIP (Environmental Quality Incentives Program). Won't get a rent payment, but would help with planning and installation costs.
PS- Hank and I could be made available for bird "surveys"...
