There’s nothing better than doing something you love – and making money from it. Here’s how Robert Campbell added $20,000 of value to an otherwise mundane and unexciting stairwell. A 2′ x 3′ opening was created to bring more natural light into the 18′ stairwell. $150.00 for paint;$450.00 for the 4′ x 6′ airplane pic – which a graphic artist helped me create. PS: Robert Campbell learned a long time ago that creating beauty is an excellent investment in terms of both time and money spent – and that home buyers will pay up for it.
