Char Selling : FFXI General Discussions

I recently have quit the game and would like to sell my char. I have no clue how to, what site to use, or how it will work. I was also wondering how my credit card would be safe. My char is a drk 43 main 30 war 10 thf 20 nin 15 drg and a few others in the teens. He has about 500k on him and over 200k in equips. Anything would be appreciated, please help me out.
