It depends primarily on WHERE you're located. To use an American example; someone working with the Ivy League citizens of Boston would see far more than the gal in the park that's dressed a bit dumpy.
As with any industry, packaging and location are the two keys, when it comes to the former we must consider if or not the person sitting there and offering their services looks like they are worth and worthy of our venture? How are they packaged as a product and do we find it appealing?
Many long years ago I worked for a man named Jim Ward, a
jeweler based just outside Beverly Hills (those in the know will understand why I italicized that term

) One year Jim was at a big gem & mineral show and happened upon some "unique" lapidary work -- seems the gent in question had made a few dozen purple penii (that is the proper plural for penis, isn't it?) from amethysts crystal... ironically, he did so in his youth some 30 years prior and rarely ever got as much as an inquiry about the things let alone a sale.
Long story short, Jim purchased the phallus collect @ just $3.00 a head and within a week had them on display in his store... a store that I should point out, sat just outside Beverly Hills but likewise at the heart of what was known as Boy's Town -- West Hollywood and the Santa Monica Blvd Gay Bar scene. It's important to understand this in that Jim sold out of the collection in under two week's time, with each sculpting selling for over $60.00 -- ten times what the original designer was asking.
The secret to his success was simply knowing his market; location plus presentation = parallel results i.e. a consumer base willing to pay the asking rate in that value is seen within it. If the Reader isn't projecting value, they aren't going to see the higher rates of pay... even for a mini-Reading @ the flea market.
