Engaged couples can submit their love stories to Done. New Yorkers will vote on the winners, who will be chosen in true collaborative consumption fashion by June 1. The wedding will take place before Sept. 15, the exact date depending on availability in the South Garden in Central Park.

"The way we looked at this was, 'what's the way to share the power of collaborative consumption?'" said Done cofounder and CEO Kevin Nazemi. "A lot of times people think about this space related to tasks and odd jobs, yet the talent of our community is so broad and immense. This is one way to showcase that."

The "doers" the couple may want to hire for the wedding include photographers, videographers, caterers, violinists and bartenders, who are among the site's near-125 members. Done's community can even supply a minister. In addition, Done will give the couple $1,000 in Airbnb credit for an apartment to serve as a honeymoon suite.

Hopefully the marketing gimmick goes well—be careful of bridezillas, we warned Done. "I'm going to put on the application, no bridezillas," Ms. Amondson said. "We accept same-sex marriages, just not bridezillas."

Done.

Done., which raised almost a million in an oversubscribed round last year from investors including Khosla Ventures, Thrive Capital and angels including Harvard Business School professors Bill Sahlman and Joseph Bower, launched with a team of 12 and 100 "doers," including Apple consultant Brendan Perreault, who in addition to making slow MacBook Pros fast again has the added bonus of being kind of a stud.

With "do it for me" startups all the rage—see Zaarly, TaskRabbit, and the just-announced mobile startup from Justin Kan—Done. differentiates itself in a few ways. It's very pretty, its doers are organized into handy categories, and it's launched with a highly-curated set of specialists.

The big difference for Done., though, is its do-gooder bent. Donations are made to Unicef for every task completed.

The company also tries to appeal to neighborly sentimentality. "In earlier times people relied on the members of their community," the website says. "You knew who your neighbors were and what they were good at. You knew they wouldn’t mind if you looked them up and called on them to help out." For money. Mr. Perrault, the Apple consultant, starts at $75 an hour. Done. also takes 10 percent of every transaction. New doers must sign up with Facebook and be verified by two friends before they can start doing.

The startup comes from CEO Kevin Nazemi, CTO Paul Covell (first engineer at Zipcar) and COO Ken Nesmith, former MIT roommates. The founders were then joined by other lifelong friends, some of whom have known each other since 7th grade, to form a team of 10 based in Soho, according to a press release.

With Zaarly's TaskRabbit's acquisition of SkillSlate, Done. appears to be the New York contender in the convenience economy craze as underemployed Brooklynites shlep laundry and piece together IKEA futons. We were skeptical when we first heard of Zaarly last year at SXSW—Demi Moore actually explained it to Betabeat, no big deal, after the Diplo show in Austin. But it seems DIFM may be  the new DIY.
