Hi Mark,
As you're using a hosting service you'll probably find a hidden file called .htaccess in your moodle root directory - if not, create one and add the following:
php_value upload_max_filesize 150M
php_value post_max_size 150M
I don't know anything about Bluehost, but assuming they allow .htaccess files (which I believe most hosting providers do) then this should override these values in php.ini for your site. Otherwise this will have no effect, but it has to be worth a try.
Hope this helps.
Tony
