Best of luck with your new venture!
What I've learned is that if you want your business to succeed (and you don't want to drive yourself crazy), you really need to be involved full time.
Don't leave it up to other people. When you are investing your money, your name and your time, then you need to be sure that you are doing EVERYTHING possible to make it work.
Say you are investing $1k monthly into your business as well as your time as it is available. And you have someone else doing the things to promote your business: networking, meeting with clients, planning, implementing. Sometimes it can feel like you are just letting that money blow into the wind (which in a way, you could be).
Best of luck,
