Ability to change your rank

[Rashed Ahmed]

Hello,

I am requesting if someone can build me a small plugin for whatever cost it takes (PayPal). The role of the plugin is to allow members to have a small panel where they can switch their primary rank with the secondary ranks. So for example if I had the ranks: Members > Donator > Gambler > Supporter and Supporter being as my primary rank, I want it so you can switch the Supporter primary rank with any of the secondary ranks I choose such as Gambler. This will make my primary rank Gambler, and my secondary rank Supporter, including the other ones I already have. Let me know :)
