I was in your position when i bought a (most likely) a much smaller company (200k rev) in a totally different industry (cleaning), the previous owner did everything manually and on paper, like EVERYTHING. I knew i didnt want to do this and also was going to get rid of it anyway. I wasnt that skilled at the "people" part of the business either (much better now) so i enlisted the help of my best friend, hired him to basically run the company day to day. Then i did what i'm good at, eliminating the unnecessary repetition, basically, i automated a LOT of the companies operations.

Now the company doesnt take that long to maintain on a day to day basis and is MUCH easier to deal with and isnt as fragile (less single points of failure). Theres still improvements to be made and we're working on that, but now it takes much less skill to be able handle the day to day, it doesnt need a CEO, just needs an administrator.

* Hire someone that is good with people, because you cant automate that.

* Automate as much of the admin crap as possible.

* For things that you cant automate, but does repeat, you can establish processes to be followed instead.

This might be totally irrelevant to you, but it worked for me very well.
