When typing your inquire, please ensure to add as much information as it is possible. Making mappings requires a lot of dedication so if your description is not clear I won't have much time to spend on asking additional questions. This is why every little detail in your description is essential.
You can also include a short video clip or a PDF/JPG files with the description if that is your preference. Or you can request a clear image templates for your controllers that you can use to label all controls with dedicated functions.
