I would say your best bet would be to sell ads direct to targeted companies. Approach local news outlets, TV stations, etc. Many times they will buy ad spots on local websites for TV SitComs, late night, etc.
hmmm..first congrats on the visitor traffic. Now, as far as picking a good cpa program, I would go with Marketleverage or pepperjam. THose are the only two I know off the top of my head that has received good reviews. Marketleverage pays twice a month by fed ex or paypal (only if you make $1000 a week). Make sure to pick a clean template for your website/blog and to use 125by125 product banner ads and place them either right above or below your page title or blog post. They will convert higher. Good luck
instead of trying CPM stuff, you could consider setting up a newsletter & getting people to sign up. after that... sell stuff to them. over and over.
