Design a mural for a small interior office wall

Well hi there, and thank you for your interest in this project! We are a small creative agency and have recently moved into a small office space that needs some serious help to turn it into a funky space with some character. In the office is a cinder block / masonry wall that is currently painted off white, and we're thinking we'd like to do a mural on it somehow. I can get exact measurements to the successful bidder, but it's about 12 feet high x 8.5 feet wide. As you'll see in the attached photos, there's currently a small couch sitting against the wall that could either stay and be worked into the mural in some way, or be moved to another wall, or just ignored where it sits. Now.. The real question here is what exactly we should do for a concept, and then it needs to be drawn up...This is where you come in. We've got some general ideas, but nothing too fixed, and definitely need some help coming up with just the right mix of "funky little design studio" and "these guys are total branding pros I want to hire" ... So this process is about the creative aspect of coming up with the right concept, as well as getting the illustration just right. Please share your portfolio from similar projects in the past. A couple notes: 1. I'm really hoping to get this rolling asap!! Please mention when you're able to start working on this project as it plays into the decision in a big way. 2. The wall is rough and that needs to be worked into this concept. The intention is to work with the surface as it is, NOT to refinish or smooth it out in any way. 3. Time is of the essence! :) Thank you, I look forward to hearing from interested bidders soon!
