He is, however, definitely looking for an Amber ale. He worked for a fancy shmancy liquor store years ago, he knows what he's after.
Well, (and please don't take this with any disrespect) I'm not sure that he does. He says he's after a German/Austrian Amber Ale, and such a thing doesn't really exist as a style. He says he likes "Fischer's", which is neither German, Austrian, or an Ale (it's a French Lager).
Fischer's is, as far as I can tell, considered either a "Euro Dark Lager" or a "Vienna Lager" depending on where you look. I couldn't find any specifics on the recipe, however. Reading reviews it sounds a little too "caramelly" for a true Vienna Lager.
If you actually want an "Amber Ale", an Altbier is as close as you're going to get for a "German/Austrian" style. But I suspect he really wants a Vienna Lager/Oktoberfest type beer.
So, if you're capable of fermenting at lager temps, I really think that's your best bet. If not, my earlier suggestion of an Oktoberfest/Marzen beer brewed with an Ale yeast sounds like the way to go.
One other thing: The only reason I'm speaking in terms of known styles is that you seem to be looking for pre-made kits, which tend to be restricted to known styles. It's entirely possible to make a "German Amber Ale" by making an Amber Ale with German ingredients, etc., but that requires you putting together your own recipe.
FWIW, places like Brewmasters Warehouse allow you to put together any recipe you want on their site and purchase it, so that kind of thing is always an option. You could take any recipe from the recipe section of this site, and buy it from them, with any changes you want to make (like swapping out a lager yeast for an ale yeast, etc.).

Hope some of that is useful!
