Depends on the size of the company being discussed, I've seen some where one ran the show with time to do other IT work and I've seen others where ten people couldn't keep the status quo.
Thanks. So, it's definitely possible. what i'm wondering then is about how long would it take for someone who is already trained in design to be proficient in developing/coding a website?
I have the opportunity to learn more about web development but I'm unsure of how long it will be before I can design and build a website well. I'd love to hear what other people have learned through experience.
