Create a community where everyone shares their Bucket List. The database would allow people with similar interests get connected.
- You could build a group of people and get better prices or discounts.
- You could see someone that has done what you wish to do and ask them for help.
- You could try crowdfunding, bartering, and refine your idea or experience even more.
I think it would also be useful for advertisers and service companies as they could provide deals and advertising to specific groups that are looking for services in their area of expertise. There could be sponsorship in exchange for recording the experience in social media.
There could also be a paid "membership" service, where your money goes to an investment fund to be used in an "ultimate" list item or that would be given back to the person you pick if you don't use it before your time comes.
In order to create an active community, there could be incentives for people that help others, that complete and share their bucket list item, you get credits for signing you will or getting any other affair in order.
In the end is create a community that might make those items that seem to daunting to take on, possible.
When your time comes, you will have a treasure trove of memories and feel that you have lived life to the fullest
