How would you monetize my website?

Hello everyone,

I have a website that is collecting contacts of future brides and grooms and multiple informations about their needs (Wedding date/Mail/Phone/Place/Budget/Type of service providers needed..)

My main idea was to provide my sisters company (wedding organization) some potential customers. But with the little time she has available, she can't address all the contacts I get.

I was thinking about other ways to use this business/database but I don't know what I should try. The few ideas I had were :

• Sell the contacts to other service providers (but I have no idea how this can be monetized and how to set the price)
• Sell the mail/phone/wedding date to other company (Could be nice for florists or souvenir stores to be able to send targeted emails on the date of a wedding?)
• Sell the whole store to another wedding organizer

There are surely other ways to monetize or re-use this work, so feel free to push other ideas !

If you have experience, feedback, advices or if you just want to share what you think about that, I will be happy to read you !
