I've read when a new hobbies writes a review of a new provider it isn't posted right away. Understandable. But when a hobbies that has wrote a review about a new provider is there time length before it is posted?

It can be up to 72 hours.

As long as everything is submitted properly it can take anywhere from an hour to 72 hrs, normally posted within 24 hrs. I think your question is whether there is a specific waiting period as there is for some new hobbyists, the answer is no.

Finally after like three days my first post is finally up. I'm so happy. Check it!

Your first review is great, shame you are all the way in Atl. or I would be #2!
