(a) a five-course Indian meal cooked (by me)
(b) a poem written (by me) on any thing or person the successful bidder specified.
The station manager suggested that I assign a monetary value that would make it easier for them to advertise the "goods."
The Indian meal was fairly simple to calculate--materials plus time compared to the going rate at a restaurant. I asked Big A for help with figuring out how much the poem would "cost." He thinks the going rate per poem is about a nickel and sometimes a glass of wine and/or applause.
He's probably right.
