Any help in this matter would be appreciated.

I get my bases from local retailers. Sometimes I steal them from my wife or children. They are made by the US Mint.

I use pennies. They are very robust, inexpensive, and readily available around the house.

I have used a variety of materials for bases in the past. Cut styrene sheet, balsa, or most often just cut card stock.
I like pennies best. Started using them about 10 years ago, and don't use anything else anymore. They have some real weight to them, so your figs don't go flipping around if a breeze makes it into your gaming room or someone bumps the table. The base winds up protecting the figures to a large degree when they are in the box. And did I mention they are cheap? I get almost 100 for a dollar!

Cheap is good. Leaves me more money to spend on my tanks.
I don't base most of my vehicles.
Others take other approaches. It depends in part on the rules you use, and how much information you need to have with your models. Your mileage may vary.
