Good morning ctlsolutions,
You are in need of some phpBB maintenance and I am the freelancer who can deliver!
At minimum you are talking about modifying a couple lines of CSS and adding some html/php to the header and footer files of your phpBB theme.
At most you are talking about setting up an SQL database, installing phpBB, installing the DEMO theme you have listed, and then the CSS and header/footer files.
Either way, only a couple hours worth of work. I would need address and login for your hosting, the login for your phpBB admin, and I should be able to get the rest done from there.
I am sending a message to your Inbox from WDWMKR with details. Please review and I hope to hear from you soon!
