We are thinking about using Toolset, which is a mega awesome plugin to customize WordPress. We can create custom fields and all.
However, they need to have custom price controls as well and the bigger issue is linking these with a shopping cart like WooCommerce (or something preferably lighter weight, just a way to display charges and offer a payment gateway). Does anybody know how to do this so the total - based on what the user chooses - shows up in the cart? Thanks.
