Hello. Sorry but the demo url is not displayed for me on the project description page. But I have read that you want a gambling website for CSGO with Jackpot. And it would nice for it to have an Admin panel and a chat. And above all the website should be simple. You said the design should not be very special.
I understand your choice for a website to be simple. This goes well for a gaming site like that. Nevertheless you still need a really competent developer for this task. The one that can deliver the highest quality code. As the site features a chat it is important for a developer to be familiar with networking, JavaScript, Ajax and PHP. The admin panel requires a knowledge of UI development.
Also the developer should know how to create a web site in a simple way. Some people tend to overcomplicate things when developing websites, which all comes from the lack of experience.
I fulfil those requirements, because I have developed many simple websites like that and even more complex websites. I have been doing this for over 6 years. I have been working with networking, JavaScript, Ajax, PHP and more for over 6 years. I am familiar with UI development very well and I know several tools that allow for creating bug free simple websites in a very short amount of time.
I think people who play CSGO and gamble around it would really appreciate a great and simple user interface, which your website will feature if you accept my bid for this project.
