Aerial roof measurement software engineer

Looking for a software designer/engineer to help me measure roofs using aerial photography. There is a company that does this: www.eagleviewmeasurements.com. I have worked with this company however, want to see if I (with your help) can accomplish this also. They use this website to provide their reports: [login to view URL] May have to subscribe?? Also, there may be other sites offering similar aerial shots? Attached is one of eagleview's sample reports. I can help beta process by actually verifying roof measurements in my area. As an option, we can explore marketing any software developed commercially as a partnership. Thank you for your interest.
