Hi, I like the red.
I am interested in your project.
I have experience on website development. Special is on Opencart.
I read your requirement.I have some questions about your project.
+ Admin can add multi condition in product editor? So, have to design table in database for this?
+ on Product page, the customer select condition, we save condition to cart info or not?
+ On Cart page and checkout page will show condition for each products?
Please feel free to contact me and we discuss in detail about your project.
Hope to work with you.
