Headers, Joomla work, Code updating, graphic designs etc.

Im looking to hire someone to do ongoing work for me, I need someone who is fast and responsive and has a great eye for design. I get about 80 projects a week and need more people to work for me I cannot seem to streamline everything and need more overhead, so with that said, I am looking for someone for ongoing work, I need someone who can 1/ Work with Joomla - Make updates on websites I manage 2/ Fix code errors on websites 3/ Design banners once in a while 4/ Design misc. graphics for websites I am looking to hire a employee to work with me on a daily basis, right now I give things to my programmer, lets say 4 color changes on a listing template, and I pay him between 5-10$ to make these changes, however it takes him a week to get the code back to me and that is far to long, I need someone who is on the ball. I have hired before and people take to long to get stuff back to me, I need a fast turnaround if you want to keep working with me. I will pay $30 up front, the 30$ will cover updates needed on 2 joomla websites, just text and photo updates and entering property info on a Joomla component simple stuff. Then we can work out details afterwards, do not bid if you have never worked with Joomla before.
