Change the styling

The login page for the news section of the site is at:
http://www.operationshoestring.org/news/wp-login.php

Getting the WordPress-based news page to look like the non-WordPress main site will need quite a bit of work for which php skills will be needed. Alternatively you would need to hire a developer:
http://jobs.wordpress.net/

Even so, the two parts of the site are unlikely to ever look identical. For best results, the whole site should re-built using just one theme, but this would be quite a bit of work.
