Capacitive touch sensors aren't horribly complex. I'm betting this is something you could learn about and implement in a fairly short amount of time (6 months with zero electronics knowledge?).
For some I would think more like 1 month if you're dedicated.
Every chip has capsense peripherals these days. Even the ones that don't have capsense peripherals secretly do if they have an ADC, that can sometimes be easier to make more reliable than the hardware(Although those might be better for larger areas).
