Aside from loving projects like this (creating a custom website that isn't a simple reproduction/dupe of another site), I'm an avid gamer. I'm presuming that this website is to power a level/character boosting service, which I'm familiar with as a service.
I'm a PHP developer with mySQL and UI skills as well. I would like to use Laravel framework for this project, as it's a powerful framework which I've yet to use for a project from start to finish - only joining an existing project and adding to them. It will make our authentication & account management quite elegant.
The only drawback is I'm not a website front-end artist, but I do work on UI. So I could build a website that would need backdrop images or a Photoshop design made for it and I could implement the HTML/CSS/jQuery for it. I love using jQuery and Bootstrap to make a basic, sleek looking design with the code I work on - so I could make something that looks good but just lacks artwork. Did I mention Laravel is pretty shiny too?
On second thoughts, if we work together a bit I can produce a good website design too. Depending on the game, can probably make it good looking and themed. I know someone who could make you a professional logo and/or design for a fee.
I'm willing to lower my bid if allowed a slightly longer completion time. I'm happy to support this project once it's live, with maintenance and new features. Please consider giving this noob a chance to work with you.
