$3 for 6,000? You need to bump up that value. Let's say you want to make just $21 a day from that site or $630 for the month. You would need 42,000 impressions a day! That would be a pretty busy site with pathetic earnings. Figure out what your current average click value is. Using $0.25 a click as an example that means you got 12 clicks or a click thru ratio of .20%. Many sites are getting 1-4%, even more. Work on the design, experiment, and go for 1.5%. That could be a huge jump in your earnings. 90 clicks at $0.25 would be $22.50 a day is what you could be making right now!
