custom structure problems with permalinks

I’m having a problem setting up my (custom structure) This
problem has baffled me for days now.

I’ve gone to all of your forums and have found no one
with this problem. Why am I having this problem below?

Here is my problem, I’ve been working with my web
host provider and they have assured me that my
permissions are set at 766.

I’ve gone to settings-reading and marked my static
page. My front page is set for home, my post page is
set for blog.

The horrible problem is with my permalinks, when I
change my default setting to “custom structure”
then add the proper code from (option 2: Advanced SEO)

My home page displays with the proper URL
http://www.ezncome4u.com/blog which is my Word press
address (URL)

Also in the settings-General location my blog address
URL is the same http://www.ezncome4u.com/blog

So under the managed-pages my two published pages blog
and home; when I click on my home page it displays.
But when I click on my blog page I receive an error:
Not Found
The requested document was not found on this server.
Web Server at ezncome4u.ieasysite.com

When are brought the issue to my web host support team.
They reset my values back to the default setting.
They don’t understand what I’m doing. They just tell
me my links are backwards.

Yet under the default settings my blog page will
display but it says: when I click on (view this page)
(not found) sorry, but you’re looking for something
that isn’t there. Yet I see the blog page.

How can I correct this problem to use the custom
structures properly for my permalinks?

Is there someone I can contact because your forums are
a dead end for my situation. Otherwise I will be stuck
using the default setting.
