Help, what is the best way for me to complete my coin collection?

This is what my Fifty State Commemorative Quarters 1999–2008 collection look like, ( please click on the image ) except I don’t have the New Mexico and Hawaii quarters that were released in 2008.

I did not buy any of the coins and decided to collect by inspecting what would show up in my pocket by chance. I got the 48 but forgot to watch out for those two and probably missed some opportunities. Now, they’re not turning up and it’s been months.

Sounds silly but I guess I’m willing to give up the very principle of this particular collection and get those two quarters by whatever means necessary as long as it does not cost me a lot. Any ideas? Thanks much! : )
