There's no other people that will be happy to have it but only you since you've worked hard for it and basically, how long does it takes to obtain that amount you've mentioned? If it's not that much then just don't sell but keep it.
And at that the account is worthless and no one will waste the time or resources taking source risk.
You have made the right suggestions to ops, the best ops can do is to continue to use his account since he is not going to get any offer here.
Well, for SVIP 9 we need a 20.5M XP, which means we need to wager $20.5M dollars... I guess some people can do that in less than a month (I saw one guy doing it, with +$1M wagering daily...). But it's not about how long it takes, it's more about how much money you lost along the way and does bonuses you got (and BC has a lot of bonus drops for people who wager a lot) cover all that and brings some profit.
By the way, I doubt that OP is the owner of this account in the first place.
Unless he really wants to sell it and just plainly accept all of those lost wagers that he had made. But thinking of all the efforts and bets he's made to reach that, is he really going to sell it that easily? And yes, likely he may not be the owner of it, and possibly that is just a commission sale if ever it goes successful.
