Search marketers are always in search of quality links from authority domains. Wikipedia is the most wanted in that category. Creating page and getting links from the page is quite usual and involves lot of works as it is hard to pass the admins approval. This is more applicable for the local or global brand businesses.
What for rather new sites?
There is a way. Suppose you have a company site with say more than 10-12 pages. Try to incorporate a BLOG to your site and keep updating with quality posts and industry updates. If you have targeted a Wikipedia page from where you wanna get a link (this is from external links section) say from Mother Teresa Page, you can cover a long article as how Mother influenced your life and career from good to bad. Realistic post would attract more as if you have any association with the organization, you can mention the same in the blog.
Try to put the Post link in the external section. Your Blog would get real value and any post for your clients would also get natural value by means of visitor counts.
