Regarding Rest. Menu - no pay

Wix Arena Designer need help - Have a food Caterer client that wants to have a restaurant menu ( so I loaded the Wix App) but he does not want it connected to pay online. He simply wants people to be able to select the products add them to a “cart” and submit via email the order to him …only way around that I can figure is either custom code or set up a custom form which is not ideal as it will be a separate from the menu app where the info is located - leaving a more abbreviated description and options on a really long form. I need to know if there is any way to code this for him in a not expensive over the moon way…and who can I go to for it…not thinking this is a freelance gig - but maybe…I’m just a graphic designer with some CSS and HTML code under her belt.
