Hi! My name is Mike, and I’m really interested in your project as it is exactly within scope of my expertise. I’m a highly skilled .NET Developer, specialized in various web-automation tools and social networking apps (including Twitter, Facebook and so on, API-based or not).
I've successfully developed a lot of apps for social networking, automated posting and commenting, data extraction, web-crawling and so on. Some of them were not trivial.
It looks like this is what you're looking for.
I’ve carefully read your requirements and can create a high-quality desktop app for your needs. Some technical aspects should be agreed, but generally it’s clear. I’m sure you’ll be satisfied with an efficient app, developed in a timely manner. Please, contact me to discuss the details.
Mike
