Dan, Doug is right it is a lot more to it then just picking up a welder. You will need the right clothing, a welding helmet, correct power source and materials.
Now in saying that if you want to get into welding or reconnect with past experience. I would check out some local courses or a friend with some time to help you out. Reading is great but with the potential for injury a experienced helping hand is the way to go.
The cost you would see from the wire frame guys here will be very competitive and they will have an eye for what you are trying to achieve with good results. Their passion is in doing this work.
I do wire frames but I do not work in steel. I have chosen to work in aluminum. The steel frames with powder coating are excellent with a ton of color choices also and mine are 3-D format weld less so mine would not be a fit for you.
Doug or Dan would be great to work with and they do very nice work. I am sure there are a few others also.
Hope this helps
