An ideal way to attract young marketing talent for a small organisation is to give them ownership of the marketing strategy and tactics for the organisation. Unlike larger organisations where there may be a hierarchy of managers and/or red tape, giving a young professional the chance to take charge and drive the marketing for a business is giving them the opportunity to build on their resume, skills and portfolio that may not be possible in a larger organisation.
Also, providing them with the opportunity for professional development is also a great way to attract young marketing talent. For example, if a young marketing professional wants to up-skill in the area of public relations and media relations, organise for them to have one-on-one training with a PR professional or pay for them to attend an industry conference.
I am fascinated to know what is behind your desire to attract young marketing talent to a small organisation. As experience, capability and talent are not always associated with ‘young,’ also the age of your potential marketing employee may not prove to have any genuine relevance to the commercial success of your small organisation.
If you are (as it would seem) a young individual planning a start-up but lacking adequate marketing skills you could do worse than to outsource to a seasoned (not so young) marketing mentor in the short to medium term.
Once you have established cash-flow and some commercial stability, then you can rationally take on the expense and responsibility of up-skilling a less expensive younger (and talented) marketing employee. I would never suggest that age and talent are connected but experience will almost always trump talent (at any age).
