Hiring Interior Designer

Has anyone ever hired an interior designer? I am not the best at decorating and honestly, between work, school, and family, it’s just hard to find time to really do it all.

I’m not sure what all we want done yet. I know our master bedroom, living room, and dining room. Maybe help with an office area and two small bathrooms?

I know prices vary depending on the area and what I want done. But, has anyone ever hired a designer? What was the cost, and was it worth it?
