That last one of testing1two's looks really interesting, that's the closest you will get to flush anywhere. The thing that I wonder about is it's tactile response. His first one, however, looks like it would definitely be a good choice.
You do indeed have a lot of options. There are a lot of companies out there, you just need to know how to find them. There are also companies that will make one totally custom for you, but you don't need that since you're not looking for anything rare, and that's gonna cost a lot.
By the way, I was browsing All Electronics, and one of [Invalid or Expired Link Removed] might be interesting. They are both momentary and normal toggle, so you could use it as your tremolo, but also as a normal kill switch when you wanted. Not to mention that rocker is only $0.5!
