What Is the Best CMS for Community Like Website?

I'm thinking of building a community website for bloggers where bloggers can create their profile, Submit their blog & latest update, meet with new bloggers, Ask questions related to blogging and Write community blog post. I've researched a lot about Drupal and Joomla, But still confused about which one would be best.

* I'm not a professional in PHP, ASP (Only Basic Knowledge) * I don't want to spend more than $1000 for this project (So hiring pro is limited)
