"We don't need pots and pans or a registry, we need a wedding," Caldwell, 28, told ABCNews.com.
And so Caldwell and her fiance, 36-year-old Cole Parker, developed a Web site, Dollarforawedding.com, advertised it to family and friends through Facebook, and saw the donations pour in.
So far, Caldwell has received approximately $750 toward her $2,000 goal but said she's likely far outdone her original estimate with several sponsorships she's received, from a photographer offering her services in return for free advertising at the wedding to a florist proposing a similar deal.
"We weren't trying to have a lavish wedding; this wasn't a get rich plan," said Caldwell. "This was just to help us with a small intimate wedding with no more than 75 people."
The idea for the site and the guest-funded wedding was born out of her own family and friends, said Caldwell.
"This is both mine and my fiance's second marriage, so we were thinking about just going to a court house," said Caldwell, who has been with Parker for nearly two years. "We didn't want a big shebang, just something small.
"But our friends wanted to be in the celebration and asked us what we wanted help with," she said.
Money, it turns out, was what Caldwell needed most.
She and her husband-to-be, Parker, co-own Atlanta-based CorporLLC.com, a company that helps entrepreneurs get their business ideas off the ground.
Many of the individuals who have stepped forward to sponsor her wedding free of charge have received, in exchange for their services, free consulting or help in marketing their own businesses.
"We're being creative and using our talents," said Caldwell.
Any income the duo makes, said Caldwell, goes straight back into their business, leaving them with little spending money, which, combined with the ongoing recession, led her to think outside the box for her own wedding.
"The recession had a lot to do with it," said Caldwell. "I've been married before, so I have the $1,000 china and whatnot; I didn't want our guests to feel the need to buy that kind of stuff."
In addition to the photographer and the florist, the site has garnered sponsors for her wedding dress, a dessert buffet, a jeweler and a place to hold the wedding, thanks to her flexibility in having a 2 p.m. wedding on a Wednesday in exchange for giving the venue some free advertising on her site.
Caldwell said that the traffic on her site, which was given a boast by the local Atlanta paper's story on the couple over the weekend, has been booming. Once visited 50 times a day, the site has seen traffic in the thousands, leaving Caldwell "sure" she'll achieve her goal of a perfect -- yet inexpensive -- wedding.
"We still need a baker for the cake or cupcakes, outfits for the ring bearer and a limo service to take us there and back," said Caldwell. "We haven't even considered a honeymoon because we can't be away from our business for that long, but we were thinking about staying somewhere in Atlanta, so maybe we'll get something from a hotel."
