Taken directly from the realitytvworld article:

Here is the casting call description for the casting of the next Average Jane:

The network is looking for "smart, witty and engaging women with great personalities" who are looking for "something more substantial than just superficial physical attraction." Likewise, the producers are also looking for "charismatic, intelligent, successful bachelors" interested in meeting a woman who has much more to offer than just "model" good looks.

This is of course a spin to attract contestants. Let me translate to what they are really looking for:

The network is looking for "extremely fat, ugly, or otherwise freaky looking women with unpleasant and bitchy personalities" who are looking to be substantially exploited and made fun of for their atypical looks." Likewise, the producers are also looking for "charismatic, intelligent, successful, and most importantly, shallow, bachelors" interested in meeting a woman with "model" good looks.
