I see that you have posted in ODCA's foam unfold request thread. That's probably going to be your best bet for this. Our armory contains files and unfolds graciously done by our members and generously donated to the cause free of charge. As such there are many holes in our collection. If nobody has responded to this yet it either means that nobody has the base model for unfolding or nobody wants to take on such a challenge at this time. It could also mean that someone is working on the unfold but simply didn't post that they were doing it. Often unfold requests are simply completed without any indication that the job had been accepted.
ODCA does a good job with his unfolds but unfolding models and optimizing for foam takes a while so you might just have to bear with us for a while. I am fairly inexperienced with unfolding but the few things I have unfolded took me several hours and they were only small parts. A whole suit could easily take a week or more.
If you don't want to wait a very vague amount of time, you could try unfolding it yourself or just start work on props/weapons and things.
Also we would love to see what you have so far! I love seeing elite builds!
