Custom Program -Price check and New Products Checker

2 Part Project Part 1- I am looking for a program to be built . I need a program that goes to my website and 3 of my competitors websites and searches all products to see prices. Then it needs to send me a excel report with the findings. On that report I want a comparison that looks like this SKU, Cost price, MYWEBSITE PRICE, COMPETITOR1 WEBSITE PRICE, COMPETITOR2 WEBSITE PRICE, LOWEST PRICE % BELOW ours (in red) / or Above OUR PRICE (in green) I will also need a back-end that I can log onto to see history. PArt 2 - I want in that program to go thru the 3 sites I provide and scan the website for any new Skus that they add to their catalog. We want Sku, Price, Title, description, URL, Date added. We need this emailed to us as well as having a back-end that we can log onto to see all of the results and history. We want a company that will guarantee their work in case something stops working or we need to pay to have upgrades made
