Which decoration company should I look for to decorate my house? What does the budget include?

My house is beautifully decorated. I didn't know which decoration company to look for at first, which was very tangled. Because of my busy work, I want to find a company with good quality and good reputation. After a friend introduced me, I chose extraordinary decoration. My house 1 18 flat, the price is not expensive. I feel quite satisfied. Choosing a big company is more worry-free.
