Nothing working

There is a learning curve to this stuff 🙂 There is no one to contact at WordPress; it is free, community supported software.

Start here: https://codex.wordpress.org/WordPress_Lessons

Pricing? You need ecommerce to sell things. Try https://wordpress.org/plugins/woocommerce/

And then you need to go to ThemeForest where you bought the theme for direct help with the theme. These forums are for free themes available in the WordPress theme directory at http://wordpress.org/themes/. See http://codex.wordpress.org/Forum_Welcome#Commercial_Products

If you can’t do the work yourself, consider looking for a reputable person on freelancing sites such as Elance. (FYI, it’s not a good idea to respond to unsolicited emails from forum users offering to work for you.)
