Physiotherapy, the devil in disguise (deutsch auch möglich)

PhysioManufaktur Lüneburg (Lüneburg is the city i live in; I'd like two versions where one uses the letters M and K for adding my name (Michel Kleymann) and one without. The one with my name id like for my business card)

I'm a physiotherapist working with my hands mainly. thats what the manufaktur is supposed to stand for. creating something with your hands. health in this case. it actually sounds better in German.the thing is that my method includes a lot of pain for the patient but is super effective. Im working my way through the muscle an fascial tissue which is causing the problems. so my customers include all kinds of people, everyone who suffers from pain, which includes almost everyone in some part of their live.
A new idea that came to my mind is that, since I have manufaktur (manufactory, factory) in my business name, one could use cogs symbolizing a functioning body. for anyone who wants to give that a try

Im thinking about warm colors like a sunset or a fire mixing into each other but if you have different ideas fire away!

lots of nicknames my patients give me include the devil or demon, partly because my methods hurt a lot (im pretty good at finding their weak spots) and because of my red hair. thats why I think it would be funny to hide a little devil or devils tail/horns in that logo. not too obvious cause that might scare people away. not a must have but rather a nice to have.
furthermore the furniture will be mostly of wood in organic forms, thats why I thought warm colors would add nicely to this style but im in for any other ideas. i don't want to give too much away so you have a lot of free space to work with but if there is more information needed just ask
Im trying to explain again what i mean with my name in the logo
for the main logo i dont want my name in it because there are going to be a few freelancers working in my office that kind of have their own name and in case i want to sell my business in a few years it gives more possibilitys not having my name in it.
for a business card layout i do want my name on it though. my idea there is that you could integrate my name (Michel Kleymann) into ManufaKtur using the letters M and K for my name putting it below Manufaktur.
