Like I said, I'm not knocking you. So, don't take it the wrong way.
Its just that; if you're going to post something on the web, as an advertisement for your business, you'd (well, me anyway) would want it to look as sharp as possible.
Who says you can't paint the walls??
Any landlord would love to have his place painted.
Hell, just do it. Don't even ask.
A couple gallons of paint can't cost more than about $35, you've got more than that in cables laying on the floor. Spruce it up. Give it a little WOW factor!
Just a suggestion.
