CKEditor 3.3.1 (revision 5586) - Problems

I have a website where i use "CKEditor 3.3.1 (revision 5586)" to manage the content of all pages. In this website, i use many styles that are defined in my CSS files. THE PROBLEM IS : - CKEditor doesnt show the styles that i have in my css files - So, we cant select the styles to use them. Only way, copy paste to keep using a style? --> NOT GOOD - When i add a link, the link doesnt use the style of my CSS file - We see EVERYTHING in black in CKEditor, so we dont know how it is going to be in the front end .... If someone knows how to fix this king of problems in CKEditor, please contact me ... I'll send the website and admin URL by PM if your price is okay for me ... I dont know how long it would take, so i will consider that the lower bid is the correct price for this kind of job ... looking forward to finally fix this problem ... I need to find someone by the end of the week ...
