I’ve experimented with this MANY times. I still have someone do a little graphic design for me since he is amazing, and works cheap, but for the most part I’ve learned that I might as well figure it all out myself and get it done right.
Every time I think I’ve found somebody that can take care of a campaign for me, or build a website that I want to do, but don’t have time for, it turns out that it comes nothing close to what I had in mind.
In a way, it has been a good thing though, I now know how to do a lot of things that would cost me a lot of money to be done by someone else.
I’m not saying it can’t be done, I really wish I had people that could do things the right way, but it’s a rarity to say the least. It probably doesn’t help that I’m a complete control freak over the day to day operations of my business
