Wow...thanks everyone.
Pat - that's a beautiful figure. I really appreciate the pictures, I think they do a better job of selling the figure than the ones on the Medallion website. I'm going to be sending my artist a link to this page for reference.
Thanks everyone else for the Warhammer recommendation. I have the Osprey books, but WH is something I wouldn't have thought of on my own. I ordered a copy from HB and I'll let you know how helpful it is when I get it.
Searching for Old Glory online, I came across this:

Yes, there's a whole host of period pieces, and the above links to historical figures. Not expensive (well, relative to what I'm paying for 1:30 and 1:32

, although I don't have any experience painting miniatures. Are there people that would paint them? Where would I find them, and what would I expect in terms of cost.
I really hope someone does produce larger scale figures. I think there would definitely be a market for them.
In the meantime, here's sneak peak of the comic:

Bear in mind it's a work in progress. If you scroll down past the written pitch there's great art (not done by me).
The story is a prequel of sorts to Bram Stoker's Dracula, and answers the question how did Vlad the Impaler become the fictional vampire in Dracula? That was something only glossed over in the last film adaptation.
Yes, I'm aware that there's an argument that Vlad was NOT the basis for Stoker's vampire, but it's among a number of historical licenses we're already taking. It's a mix of historical fiction and horror fantasy. I think the more real we get the historical parts, the more believable the fantastical details will be.
Although I'm posting it on a public forum, and it's a webcomic that we plan on offering for free, I ask that you not distribute the link, mostly so that we can present it to the larger public in a more polished form.
Thanks again, this was a tremendous help.
Best,
Mark
