I am needing an checkout pane created that during checkout will do the following:
1. Check to see if any products in the shopping cart are in a specific taxonomy term and if the cart total is over $100.
2. If there are specific products and the cart is over $100 I need the module to ask the customer if he/she would like to pay the full order up front or reserve the order for only $100.
3. If they select to pay the order in full then checkout proceeds as normal. If they select reserve for $100 I need a line item added to the order called "Rental Reservation" that is a negative value that will change the order total to $100. For instance, if the cart total with shipping is $[url removed, login to view] a line item will be added called Rental Reservation that is [url removed, login to view] so they only pay $100 at checkout.
This module should also have an admin page where I can select the taxonomy term as well as specify the total in case I want to change the $100 amount. As a result the PHP code will have to check for these variables. This should be a fairly simple module to build I just do not have the time to do it.
This module once complete is planned to be given over to the open source community. Freelancer's who wish to own the rights to this module, please do not bid on this project.
