57567 oscommerce retail/wholesale

I need osCommerce 2.2 Milestone 2 installed with contribution 'Seperate Pricing Per Customer' and 'Enable or disable tax for different customers Version 1.2'. [login to view URL],716/category,all/search,separate+price (I think this might work for my needs anyway). Here's what I need it to do... When the customer browses the store (after login) they need to be shown the prices according to which customer group they are assigned to (Retail, Wholesale, VIP, Etc.). Guests need to be shown Retail prices. Also, I need all customers (Guests, Retail, Wholesale, etc.) to be able to browse the store without tax showing on the price until they checkout. Then tax would be added if it is enabled for the group they are in and they are in the tax zone. I installed oscommerce and tried the above contributions but was not able to work out the bugs. I'm not a php/mysql guru. It may be something simple for someone who is. You may be able to look at my install and correct the bugs. Or you can start from scratch with clean install. I just need the store with all bugs worked out and functioning like described above. I will need the complete working store (with modified files) in WinZIP file with install instructions. (I'm familiar with manually installing oscommerce, setting paths, and creating the mysql database, and running additional queries on the database if additional tables,etc have to be added). However, If I can't install it correctly I will also need installation. I will do other customizations. After the above is working correctly. Thanks, Phil
