Hi,
I am an experienced software developer, and I am highly expert in Java (Java SE, Java EE, and Java ME). I understand that you want to have a staff registration form in Java Swing, and it must utilize the classes you attached, and have some validation rules as well. I also understand that it must look like the one in the attached document.
Just so you know, I have a lot of experience in Java Swing, such as all JComponents, LayoutManagers (including GridBagLayout), and EventListeners, which are all required in your project as I see in your document. I have also worked on a lot of Java IDEs, including BlueJ. That's how highly confident I am that I can do your project. I am a dedicated developer, and if you want to work with the best, you got to work with me.
By the way, I have worked with British people before, and they are very kind to work with. In fact, because of you being British, I am willing to negotiate on the price.
Respectfully yours,
Mark
