In my sentiment, a $600 workstation might be working for your personal home use but it's not going to work for your business. You need to use the professional ones and it might run you from $1000+ per workstation. I know that your business might be different from the others but in my experiences, my manager and I always order a laptop or a workstation, not include the monitor, like Gateway, Dell, Lenovo, etc., that runs $1,600 - $2,300 to get what we need. So, I think you're better to think twice about your budget and the contractor you mentioned earlier which run $38K.
