The reason we ask buyers to post a budget is that there have been too many complaints from artists that apply for positions that do not have a budget only to be told that the commissioner has a much lower amount than expected. By posting your spending limits this eliminates the problem. Because there's a lot of subjectivity for pricing artwork, this was the happy medium that was agreed upon. Please note that just because you post a spending limit, it doesn't mean you have to spend that amount if you find a suitable artist to do it lower. It's so that artists know that you're willing to match their prices for artwork.
