This model will only work for streaming idea generators and pools of such ideators.
If there is a stream of ideas (like mine, for example - see http://better-life.ru/my_ideas.html - in Russian), and the generator can generate a stream on any given topic, he places the stream of his ideas on the site.
Next, the site invites other ideators, experts and people with critical turn of mind to work out basic ideas with criticism and additional ideas in order to achieve a mature idea, that is, a concept with worked out details and objections, reinforced with additional ideas. As a result we get an "ideas' crystal" of a high value, it can be implemented relatively easily and efficiently.
Then the marketing person comes into play, who decides who can implement this idea or contribute to the implementation - the definition of target audiences. Other participants can help too.
Next comes the sales copywriter and creator, who creates creatives and other materials that promote the idea, aimed at each of the target audiences.
In parallel to each idea, a fan club is created from people who are enthusiastic about the idea. This can be done using sites such as change.org, a creative (text, video, etc.) for which a marketing person and sales copywriter also create.
Then, with the help of fans pool for the idea (they can also improve the concept and add ideas to the kit promoted by those who can implement it), email, telephone and other types of motivational campaigns are launched, aimed at each of the target audiences of those who can implement the concept or fascilitate its realization (for example, specific mass media).
When the idea center receives a lead: a response from some of the target audiences, with an interest in negotiating the implementation of the concept, a professional sales expert enter the business, the purpose of which is to conclude a contract with the entity that implements the concept, on ideological support for the implementation of the concept using a pool of idea generators, including the author of the idea and his associates who took part in the creation and development of the concept.
Thanks to the ideator pool support, the project will be implemented much faster and more successfully: that's the sales point to motivate the client. Usually in the process of implementation there are numerous pitfalls. With a pool of ideators, they will be quickly overcome thanks to ideators' creative potential and enthusiasm.
Also, at the same time, the services of a pool of pro ideators are sold to solve other problems and tasks of the client, as a comprehensive service for the prosperity of his business or other mission: the clients can be not only business, but also non-profit and government organizations.
Within the pool of experts, there should be a rating system that estimates the level of the qualifications of the ideators objectively in order to determine the level of remuneration that each one will receive.
Ideators' pool gets a part of profit, shares in the company, options, pay-per 100 ideas generated, a month/year of collaboration, on a mixed basis, or on some other basis, by the contract with the concept implementor.
Thus, for an ideator, his idea is only an advertising, demonstration for his talent, to let a sales person to conclude a contract with the concept impementor.
Also, for non-pro idea generators, I propose to create a course, allowing them to develop their talents, and become pro, to participate for money in the ideators' pool. Self-made talents can be qualified as ideator experts for renumerated participation without training.
If you like this concept, invite me. I am a serial ideator (over 700 free ideas at http://better-life.ru/my_ideas.html - you can Google-translate them from Russian), I have business experience since 1991 (since my childhood). I have been thinking over this concept for many years.
