if you are an amateur and only recently starting out your content will be most likely banned, read their rules properly and wikipedia doesn't allow anyone to make use of their platform for profit.
Wikipedia is an encyclopedia, not a personal home page or a business list. An article topic must be notable: covered in detail in good references from independent sources. Do not copy-paste content from other websites even if you, your school, or your boss owns them. To create an article, try the Article Wizard.
It's hard to get posted on Wiki! Trust me I've experienced first hand! However, by following their strict rules you'll get by. But first things first, avoid having a content that blatantly promotes your site. Also, Wiki values your site's verifiability, so before submitting your site make sure that you've been published or shared to some reliable independent websites as these will serve as your references.
