Converting 'Vampire Slayer' model into a HL2 skeleton

I’m just wondering if there’s someone kind enough to do this for me.
I have no experience in this stuff, and I’m looking for a HL1 Mod ‘Vampire Slayer’ model, specifically, the Father D. model.

Planning to use it as a custom model for JBEP3, since I haven’t found anything else that suits.

Bump, anything?
I got the model right here if that’s the issue.

Then again it’s not exactly a HL:S model.

There are a few ways to do it. But overall, it’s a painless task if you know what to do.
