Really need help skinning.

Ok, basically, I want to make a personal skin for ONE person. If there is a tutorial on that please send me a link to that too. Here is where I am stuck, I use another person’s personal skin on one person, and edit it (making it so that I am the one who created the new skin. Not stealing.) and I dont want to be under their name. So, I change the folder and the vmf’s but I don’t know how to edit the VVD’s or the VTX’s or any of that good stuff. What programs are used to make a skin for ONE person? Not a mass reskinning like all the other tutorials tell us how to do. Please tell me and thank you in advance.
