At the price listed you might be better off hitting the jobs forum and looking for a clothing set to fit M4 or Ryan. Humm, might even be able to hire someone to Make a morph for one of the casual male figures (with fixed clothing). But the clothing idea has the benefit of allowing you to use various character morphs, instead of all look alike clones in your renders.

 

Rigging this figure would definitely be the last way to go, IMHO, since it would involve not only purchasing the figures for yourself, but also for the rigger, unless he/she has them already or is willing to make the purchase, which I would doubt unless you are willing to pay a lot! also, rigging a base figure is rather a lot of work, especially one whose topography might not be optimized for Poser or DS and since it's unlikely that the rigger would ever get permission to re distribute the figure, the cost would be, well, let's leave it at expensive! I am saying this under the assumption that you, yourself aren't an experienced rigger, or you wouldn't need to ask about it.
