I've made a model for Insurgency, but I can't wrap my head compiling it for Source?

Heya there everyone!

So I'm in the situation where I've made a joke model I'd love to have ported to Insurgency, but after sitting for a couple of hours at this point trying to read through various forums and wikis to see if I could get it converted into a format Source would read, I've kinda given up.

I don't have any prior experience using Source, but I thought one of you guys could give it a shot to help?
If someone could give a comprehensive guide, or possibly convert it for me, I'm sure we could figure something out in terms of credits on the Steam Workshop?

Anyway, I've got a link to the files I've got.
Not quite sure which 3D format to push, so there's fbx, obj and 3ds.
As for textures, it includes the legacy spec, normal and diffuse.

Here are some pics for the heck of it.

I kind of mention it briefly through my guide at the last section but it's to port to Garrysmod. Just vice-versa and instead of the gameinfo being Gmod, be it Insurgency I guess.
