FilmShack,
Are you marketing to PBS or HGTV or both? If you keep it the way it is then PBS seems plausible. If you dumb it down then HGTV,etc could work out--especially if we enter into a deep recession later in 2007.
According to my TV criteria for any chance of success, you have down, for sure, three of the five characteristics that matter to me (I'm male):
1- Looks (yes)
2- Personality (yes)
3- Connections (??)
4- Talent (yes)
5- Expertise (you could be reading from a script and are completely in the dark about the subject matter---if you are you have me fooled)
Of course, number three on my list generally should be antecedent to the other four

Will be looking out for you.
