Need help on potential grow room

Looking at getting a 2' x 4' grow room. The two problems I have is that I would need an electrian to come in to my house and install another outlet because they are all tied up with other stuff like my comptuter, tv, and small grow cabinet. I would be getting a 400w cooltube.

So my question is how hard and big of a job would it be for an electrian to come in and would he have to install a 110v or a 220v outlet for the 400watter ??

Very simple. Most rooms have a dedicated service of 15-20 amps. If I remember right I believe a 400w pulls 4 amps. As long as you don't have a 70 inch tv and tri monitor computer that pulls a ton of power I think you will be fine. Shouldn't be more then $125 dollars for equipment and time, at least in my area.
