Hello, I need a programmer to make a software program for me. The program must check prices on different kind of websites (Dutch sites). It must compare the new price with the old prices. Lets say I take amazon for example. I only have to enter "amazon.c...." and the program search a possible outcomes of this site with a price by a product (amazon/.........). So that I do not have to enter all the products by manual. When I push the "refresh" button it scans the new prices and compare it with the old ones. Then it must alert me when there is a price change, like drops of 5-10%, 10-20%, 20-30% etc. How long will it take to make such a program for me and what are the expected costs? I hope someone will help me.
