need vb developer for busy customization

we need a module for Internal Add-Ons - Internal Add-Ons are invoked from BUSY application and are visible in the application just like any other menu. When you open an internal Add-On then you do not need to specify the company whose data you want to use. You just have to open the required company in BUSY and then you can use the Add-On, which will be displayed in a menu named Add-Ons.
