Hello,
I'm interested in working with you on this project. I consider myself experienced in regards to C# programming, having used it for both personal projects and in paid work during the past few months. I've read your project description and I am sure I can finish it without any issue. As a rule of thumb, I also deliver well-commented source code when the project is finished, to allow other people to extend it if necessary. We can also arrange a quick demo before accepting my bid if you'd like (in which case, please send me a message as soon as possible).
Thanks for your time,
Bogdan
