Can you be more specific? Are you taking about one room, or a whole house? Are you handy with a saw and hammer, or will you have to hire the work? What type of budget do you have? What are your tastes or preferences? Your question is too broad to answer but perhaps if you clarify it and narrow it down the readers can help you.

Just looking at one room. I am not sure how it will be done! I am not super handy so I suppose I would hire people but not even sure what kind of people I would hire. Is there one type of pro that would handle everything?
