But nothing can make you feel more out of control, or in over your head, than a home improvement project gone terribly wrong. Consider whether the paint job is really as easy or as hard as you think. Taking the time to understand your materials and research the best way of doing things can take a lot of the edge off -- and so can getting outside help.
A licensed contractor, using high-quality materials, can double or quadruple your price. On the other hand, so can a few rookie mistakes or sudden panics. Likewise, interior designers' fees vary widely, but if you don't have a head for design, color or the technical aspects of either, you may be better off getting a consultation.
Which is more important: The pride you'll feel if the paint project goes well, or the wonderful feeling of living in a space that perfectly tells the story of your family? Only you can decide. Don't be afraid of DIY projects, but do think about whether you'll be satisfied with the results. What matters is that you feel happy and comfortable in your new home, no matter who does the work.
