Need admin url changer plugin for 3.5.1

I have been searching for a solution to my problem for over an hour and it should be a simple find.

My client keeps getting these:

SECURITY ALERT: Lockout Notice
This notice is to inform you that someone at IP address 188.143.232.45 tried to login to your site “Hope I Don’t Die Before I Get Old” and failed.
The targeted username was admin
The IP address has been blocked for 60minutes.

I know hackers are hackers and they will continue this but my clients are getting upset…they get 3-10 of these a day.

I don’t mean to say the “J” word but in Joomla there is a plugin or module that will just let you change the url from mysite.com/wp-admin to mysite.com/whatever I want.

What I have read through on the site are threads that are a) years old b)aren’t compatible with 3.5.1 c) want me to get into the code and change things that way – which btw doesn’t work for most users as they remark below the instructions.

Can someone just give me a simple plugin that will change ONLY the admin login page?
