Who here can help me get a poser-ready vehicle?

I'm looking for some help creating a cargo vehicle kind of similar to this http://www.oldcrowmodels.co.uk/25mm/provider/provhl.gif

or this :

or this:

And a water craft like this:

but with a gun turret at the rear and maybe a station for driving in the front. But it would have to be big enought to hold a 1/2 dozen or so poser figures so there would be room for action.

I'm not looking for exact copies of these vehicles, I don't want to steal the design, but they make good concept pictures and are pretty much what I've been looking for.

Thanks for your help!

Cool site! Are all of those models from David Drake's "Hammer's Slammers?"

I dunno...I thought I saw a link to his "Hammer Slammers", but I don't know enough about the site. I emailed them to see if possibyl they had meshes for sale since these are all "real" models.
