I have a large amount of experience working with phpBB based web sites. I can have this mod as well as the eXtreme Styles MOD that it requires to function installed for $20 in under 24 hours.
I have done many kinds of MODS on phpbb forums, very familiar with phpbb admin panel, ftp, and all there is to implement mods. Can take <20 as your stated budget.
I am an expert and PHPBB and the scripts as I ran two PHPBB boards and moderated three boards before. Also I had to install scripts and this is similar to one of the scripts that I have installed before
