if you plan to quit eve, there is no need to sell your char for isk, since you dont' need isk anymore. I'd just sell the whole account with assets for fg.
The current price difference between a skill extractor and a skill injector is ~ 330M. You can extract 155M sp from your 160M character. That's 310 LSI's or ~102B worth. It looks like a lot of your assets are in skins, they might take a while to sell for a full non-discounted price. But assuming you liquidate your assets and actually receive 172B isk on hand in addition to your LSI's, that's 274B isk. At 500fg/B, this would convert to 137,000 fg. That's the absolute minimum of how much you should be able to get out of this.
BUT, if someone wants your actual character with the skills and character name not being unattractive to them, plus assuming a higher isk/B price, I wouldn't be surprised if someone paid a 30%+ premium above the bare minimum.
