Create another site that would have more appeal to get accepted in the adsense program.
You can add adsense to your seo site later on using the same account.
From my experience I can say, blogspot blogs do not get more response like blogs those have their own domain-hosting. Even, adsense in blogger has very low CTR. But it's not impossible to make some amount through blogger if you work hard. Better you consider having your own domain for serious business.
