Two issues for personal requests:
If a developer designs this for you, then you will undoubtedly pay top dollar.
For example, $200+ USD
as an example.
However if a developer, releases this as a mod, you could pay as little as say $13.00 for the item.
See how you go, and if there are no takers, we will make this as a mod for the marketplace, unless of course someone else develops it first.
