Hi, I have an email campaigning software for this purpose in past. For $100, I can fix your CSS and also show you demo of how the email will look in most commonly used email clients (Apple Mail, Outlook, Lotus Notes), most web based clients (AOL Mail, Gmail, Hotmail, Yahoo!) and finally try to show you also on most mobile device clients (Android, iPhone). Over all, I am considering charging a flat fee of $101.
