Windows Blinds, Dual Roller Shades, Silhouette

Any suggestion on where to look for silhouette style or dual roller shades? (Brands? Products? Retailers?)
We were originally looking for silhouette style, but I think they are going to be way over our budgets regardless...
We have about 36 windows, mostly 26" x 58".
How much should I expect to pay per windows for a silhouette or a dual roller shade? (a solar shade at the front, and a blackout shade at the back)?

All the quotes I got thus far are >$200 per windows, most of them are actually closer to $300+ and the total cost is over $10K! (And that's including a 20% volume discount)

I can do all the install myself. Is it unrealistic to expect something around $100 or less per window? (I don't think I can get the silhouette shade at that price, but I thought the dual roller blinds would be much cheaper, but not really)

I've looked at products from Blindstogo(Serenity), Levolor, and Maxxmar (Opera, Perfect Sunset)
All of them are way more than my budgeted price.

(I dont' even mind doing all the cutting and modification like w/ the ikea standard roller blinds, but they don't carry dual shades)
