Dont take this the wrong way.
I read your help wanted ad and I would never consider working for you if I was looking for a job.
Why? Like most everyone out there that is looking for an employee, you list what you want and list very little as far as what your willing to give in return.
Reading your ad I get the sense that you are looking for a Superman. Very few Superman out there and most are self employed.
That is why no one is calling you. It is in the end all about give and take and like most people you want to take and give very little.
Like I said , dont be too hurt by my words, just learn from them and you will do better than most.
