Touch Sensor LED or LCD

I'm looking to have two very small circuit boards designed of which I'll need, of course, the Gerber file, as well as the parts list (and anything else you can think of that I would need to submit to a circuit board printing company and other info needed to assemble the boards). But here's what I have.

The power source will be a 3.7 volt high drain battery, (fully charged around [url removed, login to view]), but I need the voltage out to be 3.42v. The first circuit will consist of, stepping the voltage down to [url removed, login to view] output, along with, a touch sensor activator. I purchased some stainless steel dowel (3/8"L x 3/16"D) that I was going to attach to the touch sensor manually, but I'm not committed to that. If you know of a touch sensor button that is around 1/4", that either lights up when pressed against, or not, (but preferably does), then that's ok too! The object that it's going to be placed in is round in shape, which was why I went with the dowels because even if they stick out a little bit due to something flat protruding from something round, it wouldn't expose any of the circuitry. But also, I need it to only function when it is touched directly, and not through dielectrics of any sort if possible. This isn't proximity, this is to be direct contact, again, if possible (meaning, not through clothes, if I have it in my pocket I don't want it to cut on if I touch the button). So this will have, a [url removed, login to view] coming in, with the [url removed, login to view]+ going out, to be connected to the device, and triggered by the 1/4" round touch sensor. It will also need on/off capabilities such as, if the touch sensor is pressed 5 times within 2.5 seconds, the LED/LCD voltage indicator (in next paragraph) will blink three times to let the user know the device is in on/off mode. I don't know if this is standard in circuitry or not, but it will also need short circuit protection, with the LCD/LED blinking 3 times when the button is pressed, not functioning until the short is corrected. So that's the first part. Am hoping to get this as absolutely small as possible, thinking 10mm x 10mm range but whatever is necessary with "as small as possible" in mind. Thin is also a plus. If these can be done on a single side of a PCB that would be excellent.

Next to it, (but separately) will sit a small (preferably) 4 or 5 bar blue LCD or LED display that indicates battery life remaining. (Think, kind of like a cell phone bar display, but with blue as the backlighting color and white as the segment color, if possible). Hoping for something around the 10mm in length and 8mm in height range (as far as the PCB goes), but nothing greater than that. A little smaller (if possible) is ok so long as it's readable without a magnifying glass, which is why I left that open to either LED or LCD. Whichever one is easier to use to achieve the task at hand. The reason for these being separate is, I'm going to have to join them by wire, and they'll be positioned separately and set in an epoxy mold, so I need the flexibility of being able to arrange them as needed while at the same time, keeping the boards as absolutely small as possible.
