Ron,
We have used tv for 2 years now. We started with Media Com, which handles the same channels as your AdGorilla. We feel that it has been very positive for our business. Our prices with Media Com were very similar to yours.
This year we took an even more aggressive step. We are advertising on the area network station. Much more expensive, but the response has been even better than with the above. Even with all the talk of the economy, we had a record year in 2008 and are on track to beat that.
I think your proposal is fair and a great place to start on TV. I would encourage a committal of 1 year and maybe narrow your selection of channels. You will see results, but you won’t see night and day results right away. If you stay with it for the year, I think you will see positive results. TV gets us in front of a lot of people. If you do the math, you are touching a lot more people per dollar spent.
A side comment to the power of TV . . . Minnesota has gained 1 operator as a result of the network tv ads, and is pretty close to gaining another.
