Hi, my name is Nikola,
I am working in a company which is currently developing a software which does the same. You pick a folder, choose photos and do some stuff on them. We are developing that in C# like a WPF software. It has a nice user interface and it is very easy to use.
For image manipulation we are using OpenCV library which is one of the best for image manipulation.
All these things I can do for you and show you my prototype in 3-5 days. We can have skype conference and I will show you my progress and you can tell me if I am doing what you want.
I may look young and inexperience but I know what I am talking about. You can see my reviews and you will see that I am good, reason I don't have reviews from C# is that I didn't get the jobs.
I will be always available to you and you can contact me anytime.
I hope you liked my proposal and I will hear from you.
With regards,
Nikola Berdić.
