Concerning this:

how the big institutions can make a major investment with our float severly decreased? 

Instutions are concerned with how they can invest an amount of capital, not how many shares they can buy. So 2 million shares at $1.50 or 200,000 shares at $15 are equivalent  from a liquidity perspective.

Also, some funds can buy based on share price  but additional funds will need to see revenues begin to increase. It's all good, but a process  that will lead to increased institutional investment over time. Getting on the Nas will get us the initial institutional flood.
