discount per category enhancing

We got Category Tree QVB Discount installed on our oscommerce web-shop but want it modified because it not function the way we want. Like if you activate a main category with 10 % discount, and there is a big and small product in that category, we need to set all in sub-cats, so we really need it at product level . So its quantum discount per product we need as well Only bid if you have a proven record of oscommerce projects and can create custom modifications or modules. I will not accept huge portfolio which has nothing to do with the project. (Let me tell you directly as a big buyer that this is very annoying most of the [login to view URL] more like spamming than bidding on a project.) So keep this in mind guys/girls, its not looking pro to copy and paste all the time, add in it your profile is much more pro thats all, Happy bidding looking forward to meet new programmers! Got lot of projects coming up.
