Help! how can I hire these guys

[Steve Sparks]

OK..so I always contract out my rehabbs with a small degree of contracting on my own part. I have found a very good painter and electrician that are out of work. I am considering just hiring them full time. I use them 1st and can sub them out to my other local RE investors when they need them..My question:

Do I need to get any kind of contractor's license to do this? I assume I will need to get insurance..My LLC is set up for Real Estate investing..so do I need to start another..I reallt have no idea how to structure this.
