Submission Form Mods

1. Is there a way to make price information optional on the listing form? In my directory, some listings are free so pricing is not relevant. (Please note that I do not want to remove the pricing field because it applies to many listings)

2. Also, in the price type drop down form, I would like to remove the “call” option and include a different option such as “quote”. Which files can I edit to change the text on the submission form.

( I submitted a similar post and added a reply myself with additional info. This may have confused the mods, so I am posting it again here)
