You might try the craigslist in your nearest big city 1st... sometimes stuff is free! Especially if you haul it/dig it up/take it all...good luck,& show us what you're up to...
I found a ton similar to your miniature one's at an anitugue market/mall. I thought they were reasonably priced too, but a cheaper source turned out to be small town fairs and carnivals. Of course the later, was yeas ago.
I've seen them at antique markets and fairs, like Terry said.
Have you looked at Ebay?...I've seen various sized lots there now and then.
Like KMS said: Ebay.

Our Army surplus in Galveston, Texas has exactly what you are looking for. I would think in Florida, you should have some surplus stores around
Flea markets are a great place to find old bottles
What kind of bottles do you need.....I have several wine bottles that I have placed around in the garden (might be willing to part with some).
We have a flower shop in Ashland, NE called Blooms Floral and Gifts. We have these in pink, aqua and light lime green glass. They are remakes.

When I was collecting bottles for hanging in my yard, I wanted more colors and shapes of bottles. I found some at the Hobby Lobby crafts store. Happy hunting!
place an add on CraigsList -maybe you could post in the WANTED or Barter sections....barter if you've something to trade. Also, check the Curb Alert section (just type in "curb alert"). I once found 12 bowling balls on a curb alert. Great garden art projects....Good luck!
Behind your local bars or drinking water suppliers. Auctions. Old land refills. Color clear bottles on the inside with transparent glass paint. We were tearing out a fence on our farm, and beneath the old posts--beer bottles. Also putting in a new septic field and ran into the ancient outhouse site. Treasure glass as it's being replaced by plastic.
