Staatz, sorry, I don't make models.
The good news is: Napoleonic is probably the best supported wargames period ever. There are probably thousands of companies that make Nap models. Pick up a copy of Wargames Illustrated and you'll find tons of ads for them. You could also try
http://theminiaturespage.com/ - it's a generic wargames site with all sorts of stuff in it, including Napoleonic.
I find that most Napoleonic rules work best with 15mm figures. This is because the battles get kinda big, and using 25mm or 28mm just gets impractical. Having said that, the best wargames models ever produced are by Wargames Foundry - and it's all in big 25mm.
Napoleonic is great because:
It's basic tactics - you have your infantry, cavalry, artillery and your leaders, and you have to deal with the terrain and the enemy.
It looks awesome - French blue, Brit red, Prussian deep blue, Austrian white, Russian green, etc, with every unit flying a standard - usually colorful and ornate (unless you're French). Painting takes a lot of effort though, and armies tend to have hundreds of models.
You get to refight historical battles - from the famous ones like Waterloo, Liepzig and Borodino, to obscure ones like the crossing in Italy in 1798 (don't remember what it's called). Countless historical battles to refight, from Europe to Africa to Russia and even North America. The cool thing about historical refights is that the opposing forces are never balanced, and you usually have to work with whatever deployment you are given.
If you are considering 15mm, the best looking ones are AB Figures. The cheapest, and not too bad looking, are Old Glory.
For rules, I highly recommend General de Brigade. It lets you command divisions of several battalions each. If you want a more abstract rule set that allows you to fight big battles like Waterloo, you can try Napoleon's Battles.
