You can make some serious money as a one man purely service company without employees in Texas or at least in Dallas if you do it right.
Here is the math
215 work days a year
7 hours billing per day on average
current rate 95/hr
Then add material profits on that.
Only problem is how long can you do that physically. I pulled it off for 15 straight years and would have gone another 5 or so except for some unfortunate events.
