Hmm .. Not sure if you are aware, but there's a failure of reasoning in your writing:
> I eliminated the ones who immediately asked for a list of features and gave me a quick price quote. It seemed as if they were in for quick cash and wanted to meet the minimum requirements only.
...
> However, you should make a point to include as many features as possible for the given price.
See, these guys are trying to meet the minimum requirements because they are being pressured to include as many features as possible for the given price. They are merely playing your game.
I should clarify: the ones I filtered out immediately because the dialogue would end with a list of a features and a price quote.
With the ones I liked, the dialogue was a meaningful back and forth and exchange of ideas. In the end I of course maximized the number of features I wanted for a given price so I wouldn't be charged later for wanting to add stuff that wasn't in the initial feature list. The ones I liked seemed too have more ideas for the site.
