Sharepoint Intranet and Extranet site

I am looking for someone to create a Sharepoint intranet and extranet site for me that will grant access to both my employees and customers. The site needs to potentially integrate with a CRM system and I need for the look and feel of the site to be fully customizable. I am looking for someone who can help turn this vision into reality and create a secure, reliable, and feature-rich platform for my business.
