Implement/upgrade/modify Order Editor to my CRE Loaded shop.

I have a shop based on a CRE Loaded 6.2 patch 13 that has been heavily modified and are using Norwegian language and tax so some adjusments compared to an original Creloaded shop may ocure. The development of this module wil be done on our codebase downloaded from our SVN server. I want the integration to be develloped as a module with install instructions. You will not get access to my live shop. I will implement the module based on your install instructions my self. I am available to test the moduls during the development prosess to give feedback if needed. Today I have the Order Editor v2.7.4 installed on my system and I want this to be updatet to the latest version 5.0.6.6 with bug fixes (Not with QTPro integration). You can find the module here [login to view URL] The order editor I have today is modified with 2 modules. This have to be integrated to the new module too! - Admin Comments Toolbar [login to view URL] - A small code for adding KID to the order. I have the code! We have som aditional info about our shop that may affect the order editor upgrade: - We use Norwegian tax and currency - we use customer groups. 1 group for retailers where the customer see all prices inc tax, including shipping and fees. We allso have a group with wholesalsers where all price, shipping and fees are shown without tax. (based on the customer group settings) After we update the order the order total fields shall still show with tax for retail customers and without tax for wholesale customers. Today when we hit the update button the fields for wholesale customers are converted to show with tax. That is wrong. If this happens in the new version it has to be fixed. - we have a group discount system for wholesale customers. So when i add a product to a wholesale order it has to use the correct wholesale price. The wholesale price is based on a special mode that using group discount pr category. - we have a modified COD (cash on delivery) module that add tax to this payment method. - The editor must work with all discount systems in our shop like gift card, coupong, category discount etc. It's important that tax are calculated right. I want a function/change in the add_products file: In step 2 in the dropdown list (the product list), on the end of each product line I want the current product stock to be displayed inside a (). I also want to add a button on the order edit pagge between the packing slip and back button. This button should link into this customers order list ([login to view URL]). I guess it will be some testing to get all the tax calculations right, we will ofcourse help to test it and provide you with info if something is wrong. Please be sure that you understand complitly the project you are bidding on (if not ask us before bidding). We are looking for an creloaded and php expert that have a deep understanding of the crelodad cart code base. Please don't bid if you are not 100% sure that you can complete the task in time. If you deliver only a half finished product you will not get paid.
