Hi
First of all I'm not portuguese but I can understand you pretty easily (I'm Galicien (Spain) so I can understand yo upretty easily)
I can help you with the styles of the page, I'm a web developer that has been working in lots of projects so far. I can help with you rstyle on the cs:go page and fit it to your needs.
I will keep in contact with you daily, sending updates on the development as well as constant chat to ask if something fits your needs or not. I will literally inform you with everything I do (and send documentation about it)
I work fast. Just so I know, you try to add styles to a website YOU OWN right? i mean, the problem you have is that the website doesn't look good?
Cheers
