Hi I am looking for someone who is familiar and able to develop a tool
Just similar to the components below. You should only bid if you have related portfolio to show . Thanks
[url removed, login to view] vs [url removed, login to view] in adwords: http://www.semrush.com/info/ebay.com+vs+amazon.com+%28by+adwords_adwords%29
Example of graphics for these domains stats is here: [url removed, login to view]=ebay.com&domains=amazon.com&domains=nextag.com&domains=buycheapr.com&domains=>ype=3&db=us
Of course you are able to compare organic keywords of one domain to adwords keywords of another, see the direct competitors : http://www.semrush.com/info/target.com+%28by+adwords_adwords%29 and so on.
