Do things yourself then, you have the internet and Bitcointalk to help you, ask questions here and search online to see if you can get a guide to help you solve your problem. If you grant someone access to your wallet, they can steal your seed phrase and import your wallet into their device and then steal your coins.
The wallet you are talking about here is an exchange wallet. Though you should not keep your assets in a centralized exchange, but the person helping your out cannot steal your seed phrase, because you do not have any when you use an exchange wallet, they can only deceive you to send your assets to a wrong address that they control.
You're right. The encounter was very much risky and I also don't have to trust excessively because I don't know what's in the mind of the other.
Beside they are actually operations that I'm supposed to do by myself and I only owe to research and consult without sharing my wallet screenshots as I did because there could be slight mistakes of me to had shared some of my private keys without being aware or the risky exposure.
I should really adapt to do lot of privacy works by myself because such as a helper may not be there always in helping out.
Hopefully I'm urged to had learnt some lessions out of the replies got here.
