Where do i add a custom metafield for product that is shown in the product list?

I want to show an additional price (custom metafield) to all products in in product list page. where do i add this (which Template/snippet)
And where can i put a space between the € sign and the price itself, so that it looks like “€ 10,99” and not “€10,99”?
thanks for help, flo

I’m not sure if anyone would be willing to “help” you on this as this is beyond helping, it’s custom WordPress modifications. Creating the metafield is one thing, showing it on the pages other thing and it also depends on the theme you’re using.

At this point, if you’re interested in, I can offer “paid support” for the modifications. In case of interest, you can drop me an email, I would be happy to help you to delivery the job within 12-18 hours.
