High CTR - potentially dumb question

Hey guys, I'm thinking about getting into PPC + CPA offer and such. I'm pretty new to this and I know I should start smaller and I will but I have a question for the future.

I do not know if this is average or not for ppc but here is what I would like to do:

I would like to achieve a pretty high CTR ad like around 1.5% for a $1 CPM. So, as you guys know I would be getting 15 clicks for a CPM which costs $1.

If my conversion rate for the offer was 2% and had a payout of $40. That would mean i would get $80 per 100 clicks.

So for 100 clicks that would cost about $7. Meaning, I would make about about $73 from a $7 investment.

I know there are other factors that would change things like cost of a CPM and the CTR.

But, is something like this in reality to do or it would be way harder to achieve something like this.

I realize a 1.5% CTR is pretty hard to achieve but I believe through testing and outside help I could get this.

I'm not sure if this was a dumb question or not, I'm just looking for some expertise on this.

thanks,Conno.
