Build an Online Store

We are looking for a person that have knowledge with Magento, we need to make some modifications to an extension that we buy. Requirements: * Show dynamic SKU on product frontpage on configurable products * Calculate the price of the configurable products based on the fields price, price2 and price3 * Apply percentage discount to the field price, price2 and price 3 on the configurable depending on the customer group and use for the price calculation. Information: We have a website that have a lot of products with many attributes (configurable product) we use the extension Advanced Product Options Magento Extension from mageworx . Each attribute have 3 prices (field "price" and field "price2" and "price3"), magento use only the default price called "price" to calculate the price. We have another attribute that is called "price2". We need someone that could help us to make an extension or modify the javascript so in configurable products when someone select one of the group of Hardware FInish the system bring for the others options the calculation of the price based on price2. We can have a product with a system code: sku - description - price - price 2 030 - monorail - 50 - 20 040 -monorail system - 30 -10 Catalog number sku - description - price - price 2 57485-CS - lamp - 10 - 20 57485-CS - lamp 2 - 10 - 20 Hardware finish BK - Black AL - Aluminum Etc.. So if for example black is selected it will calculate the price based on field price, but if aluminium is selected on the dropbox list or radio button, it will calculate the price using the price2 field. We have for now 3 different prices so we use fields "price", "price2" and "price3". Also depending from the customer group they have different prices, we right now use percentage discount depending on the group, so we need to apply the same discount for the price2 and price3, so when someone configure the product it will show the correct price with the discount. SKU: We need to show the sku dynamically on the product page when they choose the options of the product, all the attributes already have their own sku so its need to show the sku on this mode Attribute1-attribute2-attribute3-attribute4 the same way that magento does on their system, but we need to show this information on the product page, it could be done automatic for each option that the user choose it will show the sku on div or it could be done with a button that after the user select the options they can press the button at it will generate the sku. For candidates we expect to send to us this information: *Estimate times *Rate by project *You need to be comfortable using the extension Advanced Product Options Magento Extension, you can visit the the website extension [login to view URL] we are based on this extension and we already do all the configuration to do this. What we need: A zip file with the files required to put on Magento and instructions to install it(if is required) The programming code and if you modified a base file on Magento or any extension, you need to write notes of the changes. Bring a changelog if you need to modify a file What we are going to bring: Access to a temporal ftp access to a testing site with the same server configuration of the website. Access to admin of magento.
