I would suggest at least posting a ballpark amount of what you're looking for for this account so that people who are interested will know if they have the budget to negotiate with you or if both of you will be wasting your valuable time if their offer is not appealing to you.
And I would recommend that you allow a trusted, reputable member to view the account in teamviewer and verify for us whether the account is actually legit or not.
I am taking offers for the time being. $20K is a large number, and I need to first find somebody who has an actual use for it all. That's the point of an offer, no time wasted (a few PM's?) - if the persons time is "that valuable", not sure I want to deal with them as a customer.
I have said and made it very clear I will verify with a serious purchaser by any means necessary. I do not wish to waste my time getting it verified before finding a purchaser. I will make sure the purchaser is 100% satisfied with verification, I do not need to prove it on a public forum to many people who do not have the budget or need for this product. If somebody seriously want this, I will prove it to them, not a problem. This is a pretty niche product. You don't see eBay employees verifying that the seller has the actual item - it's between the buyer and the seller. If you're not a potential buyer, I don't need to prove anything to you (no harsh intended, just the truth).
Why in the world would I fake a $20K Adwords account? Hell, I'm sure I'll probably never find somebody to purchase this. If I was faking / scamming, I should at least try a more in demand item, like Amazon Gift Cards
