The only way I would consider TV advertising (if on a limited budget - as opposed to GoDaddy) is to develop a campaign wherein you attack your local market with ads on local cable channels. Or another good one (believe it or not) is the TV Guide channel. Not sure if everyone has this channel, but in this part of the world, we have a permanent channel 24/7 that just shows TV listings, and along side the listings they run commercials in part of the screen (usually half screen). The rates aren't half bad. I know of several advertisers who have been there for years, so it must work. Rates are in the hundreds as opposed to the thousands. And they also help you put your ad together.
One tip. If you do explore the TV listings channel, try to negotiate the placement of your ad. For instance, you might sign up for 24 spots per day. They will normally be randomly placed in terms of time of day. However, if you can, try to negotiate being displayed a few minutes before the top of the hour. Think about it. There are many people who go to the channel a few minutes before the top of the hour to see what is coming up next. IMO, top exposure is if you negotiate display times such as 1:58, 2:58, 3:58, etc.
