Design my home music room

I would like your design idea to creatively improve the look and the organization of the music room located in the basement of my home. This room is used exclusively by 4 people in my family to practice and play together for personal enjoyment. We do not do use or need studio-quality recording design elements or any sound proofing elements in the design idea. The amateur musicians are a 48 year old dad and his 4 sons. As far as instruments, we have a drum set, a keyboard, guitars as well as 4 amplifiers. Much of the music we play (and one possible design theme?) is classic rock. One of the walls in this basement room has a window and the room's measurements, layout, and pictures can be seen in the attached files. You will see in the attached schematic that the approximate room dimensions are 15 feet x 11 feet, along with a small corner nook space that could be effectively utilized somehow for storage. The final design idea should be communicated and presented in a way that I could take the designer's 3-D picture, drawing, or other suitable schematic and be able to contract, hire, and purchase whatever I need to in order to replicate the design. I would expect that in this project I would have possibly up to two to four email communication exchanges with the designer to adjust a design idea, color, etc. in order to get a suitable final design. Key Requirements of Finished Design All 5 of my guitars need to hang on walls when not in use to create more floor space. To give me some capacity, and I'd like to have 6 or 7 guitar wall hangers. The room needs a few acoustic wall panels or some other sort of sound dampening solution to reduce the harsh bouncing of sound off of close walls. Carpeting/flooring stays as is. Ceiling lighting stays as is. The canned lights can be adjusted/dimmed. No seating space is need for non-musicians / casual listeners… the room is just too small for that. Optional Things to Change Painting / wall color / wall-paper / artwork / murals are all fair game ideas to change and incorporate into a creative design. Storage , desk, shelving, can all be changed. Minimizing expenses is appreciated …. if we can in any way utilize the current desk or the bookcase shelving that is fine, but not necessary. Some sort of desktop workspace area would likely be beneficial.
