How much would you pay for a custom busy board?

For example, these are busy boards. I did not make these, they're just example pictures from Pinterest. They're for toddlers. If it were customized with your child's name, a theme (under water, jungle, outer space, etc) and possibly a photo in the "window" featured in the bottom picture (that you chose, e.g. a family member) how much would you pay? There would be different sizes, too. Possibly even the choice of which pieces you wanted on the board. Let's say for a moderately-sized (about 2ft x 2ft) board. How much would you be willing to spend on that?
