I need a promotion for my society in FB. How much does it cost and how much time is needed?
There are a number of different ways to do so.
If you have more money than time, you could spend it towards FB advertising promoting the page itself or posts that you make on the page. The amount that it would cost to do so solely based on promotion would vary as would the time for the promotion to be effective for you in reaching 1000 likes.
If you have more time than money, you could spend it developing relationships and networking to achieve a portion of those likes. But it would likely be a lengthy process to reach 1000 likes.
