Unwrap3D Pro plugin authors

I need to find someone with experience writing plugins for Ultimate Unwrap3D Pro (3.x).

I think Brad is the only one who can write plugins for his software. The downloads page says "Third Party Plugins," but I think he titled that wrong and meant plugins for interoperability with other software.

He says there is an SDK available.

Yupp, there is no SDK for it.

I asked for the plugin sdk a while ago from him, he sent it too me.
