Hello sir,
I have 5+ years of experience with Java, especially with simple Java tasks like Yours given. The idea sounds really interesting and I would treat this project like mine - every little detail would be thought about.
I will keep price really low and bring the best quality, because I have a lot of time to invest into Your project.
I will have a few questions, but communicating with You would be no problem.
I hope we will contact soon!
