Custom Product Set Up Magento Website Coding REPOST

Hello This is a repost of the project as my last provider has failed - I need someone reliable to complete this.... I have a new ecommerce project I need finishing coding up. The past provider has coded the theme up for Magento and custom "configuration" admin area for the product set-up. The idea was that the front end would be completely seperate and that the product would be passed to the Magento cart via the API The past provider has coded all the theme up for Magento. So you just need to install the theme. I need you to pick up the pieces where they left off... They seemed to have it pretty much all done. I just need you to finish off the front end and work out how to pass it via the API. Please bid and I will send you a preview of the home page (jpeg) to give you a better idea. Stage 1 - they will choose the type of product from the drop down menu Stage 2 - they will choose the width and height from the drop down menus -> price worked out based on height and width of product for example up to 7 foot high and 7 foot wide is £500.00 7 foot high and 7 foot 5 inches wide is £550.00 8 foot high and 7 foot wide is £540.00 (these are just examples) Stage 3 - they will choose whether they want automation -> if yes price added Stage 4 - choose the finish -> different price added per finish Price is calculated dynamically as shown on the front page and then they can click Buy Now to add to cart and go to to the checkout Please show your past ecommerce projects Thank you
