Hi You can mod toaster ovens, they work ok, EEVB has *lots* of info on that. When you buy your PCB you can get solder stencils at the same time. Bought as a package they are in the $10 or so range. Without buying the boards with them, I’m sure the price goes up a bit. The metal ones are a bit more than plastic ones.
Solder paste should be refrigerated if you want it to last. How long it will do sitting on the bench is a “that depends” sort of thing. Amazon will send you a (small) tube for $10 or so. The whole “can you do it” depends a bit on how good your microscope is and how steady your hands are. Again, EEVB is your friend if you really want to get into this.
