Hi, Paulo.
Those are good sites recommended by Wolfgang. But what I see in the catalogs, mostly all Seven Years War.
For 1700-1720, good suggestions have already been made. I certainly recommend Alexander Wilken as well. Other ideas:
Siegbert Wagner had many figures for the War of the Spanish Succession. But lack of German will be an impediment for you, he doesn't maintain an internet presence. I'm not sure to what extent he is still active. There are a few large sets of his on the Berliner Zinnfiguren Flea Market, although painted and a little pricey. They have some Golberg sets as well.
Speaking of Golberg, they used to stock Boverat-Bretegnier, beautiful French infantry. I'm not sure where you can find these now.
Lastly, do not rule out Heinrichsen. Old designs, yes. But many are well up to today's standards. Dr. Grobe is a pleasure to deal with, speaks fluent English, takes Paypal, very efficient. Don't completely go by the List, if it shows out of stock, ask for what you want and sometimes she still has it.
A couple examples, The Battle of Hochstadt (Blenheim) set is quite charming.

If you're looking to paint formations of soldiers, the "1/8 Package" cavalry sets from the 1920's are very nice as well, still readily available I believe. Some in standard profile, others in 3/4 profile. I have two of these, imagine them with your own paint because the castings are excellent.

Hope that helps a little.
