As far as I know, this site sells Bitcointalk accounts.
What is the calculated of any account price. If I want to sell my own account, what should I determine?
bitcointalkaccountpricer.info gives estimates of an account. I don't know if it still have an option to give an estimated price.
It does but they have been and still are highly inaccurate.
It can not determine trust value of account. But it does tell if it has green or red from the last time I check it before new years.
It is evolving all the time after it's updates are done every now and again from what I have seen.
