7 hot businesses to start now

If you've dreamed of doves at your wedding, you're in good company. Thumbtack searches for dove releasing services at special events have more than doubled since last year.

Nancy Cole and her husband Charlie, a Vietnam veteran who's trained birds for 50 years, launched their dove-releasing business near Atlanta in 2004.

"It happened because of a dream," said Cole, who was working as a baker at the time. "I dreamed I had released a white dove in a field of flowers. It felt so peaceful."

She shared the dream with Charlie, who told her about businesses that released white doves for special occasions.

"I looked into it and everything fell into place," she said. Cole and her husband work full time on their business, which has 40 birds that they keep in a specially constructed loft on their property.

They provide the birds for about 200 releases a year, charging $175 to $225 per event in the Atlanta area. Their firm, A Dove's Nest, makes $30,000 annually.
