Custom PHP Style For RP Website

Hello! I have a website up and running that I would love a new, custom style for. This is a forum based, roleplay website that is completely free to play. The website is called Standing Trials and it is based in a fantasy, post-apocalyptic world were players are faced with gruesome battles, political wars, and trials of life and death nearly every single day. I was hoping to have a user friendly style created for my PHPbb website, where all of the important links are clearly visible to players. I'm a huge fan of sidebars and was hoping to have sidebars include on the index page only to the left and right side of the main forum. I love the button look on navibars and a red/black/grey theme with some kind of textured background, or some kind of "easy-on-the-eyes" background that isn't plain color. The color scheme is negotiable! We are also in desperate need of a new banner for our website. I'm not too sure if you're able to do that as well, but I'll throw it out there! Lastly, I was hoping that we could make it so the layout of the forum looked nice on all devices and web browsers/resolutions. Please let me know if you're interested!
