Raise your bid on just 1,000,000 and see if it fills. If it does then your offer to buy is too low, if it doesn't fill then there are no shares available. You can always buy shares if you raise your bid high enough.
This is only my opinion. You should research before you invest to limit your risk. When you invest in pinks its all risk and most fail, Never risk more the 10% of your holdings in pink sheet stocks!
