I hate to be a prude but I'm going to say no on the nexromamcer. The site used is notorious for bad homebrew, but this one isn't too bad. If it werent for the subclass abilities I'd be on board. 

If you're Hell bent on being a necromancer I would be fine with looking through homebrew or helping you build a necromancer wizard. That said, you might want to look at the haunted woods for character inspiration.
