I have 6 years of experience working with phpBB software since the days of phpBB 3.0.1. I am the author of some phpBB modifications. I can install or update a phpBB forum, integrate phpBB into your website or wordpress, customize or create phpBB styles, install/uninstall modifications, fix errors or anything else related to the phpBB forum software that you may require.
For each mod just buy several gigs up to the quantity of MODs you want. For each style install, the same as mods. I can install any theme you want!
