I am in the same situation, working on http://rinconmountainpca.com/ just learn one thing at a time.

i found:
http://www.gospelcom.net/guide/index.php
especially their pages:
http://www.gospelcom.net/guide/resources/webmaster.php
this to be the best place to start.
followed by:
http://www.theoslogic.com/church_websites/

there are several places online to ask for specific answers i found:
http://www.christian-web-masters.com/forums/index.php?
to be the most helpful.

Even if you hire someone to do the website, it still has to be maintained. Web design, imho, is expensive and the money can better be spent buying a few key books for the church library and getting a few people together to write and maintain the site.
