redirect instead of access denied

Hello

I have a link going to a page in my site

http://www.mysite.com/m/events/browse/my&bx_events_filter=add_event/

This is a restricted area unless you are signed into my site.  Therefore if you get to this page and you are not signed in, you will get, "Access Denied."  I would like to change this.  I would like for users to get redirected to eighter the login form or join.php. In fact is it possible to redirect users to join.php or the login form for sitewide restricted areas instead of users getting access denied?

If you can do this for me let me know and let me know your price

Thanks
