...I'm an agnostic looking for a learned Jewish person to teach me about the Tanach ("Old Testament") and the Talmud.
Believers in the God of Israel please pray that He sends me someone fitting the description to do that...

If you ask a devout Catholic to teach you about Jesus they will tell you that he is triune and edible. If you asked a learned Jew about kosher law he will have no choice but to tell you its about what is acceptable or not to serve and eat for meals. I'm sure that you have already heard it all before. You should never seek advice about honesty from a liar, or what to do in war from a coward, or learn about wisdom from a fool.
You are better off on your own.
If you have already studied the sciences, history, literary techniques - metaphors, allegories, parables, similes, homonyms, hyperbole, etc. - and have the reasoning abilities of a second grade child, you should have no trouble deciphering the hidden meaning behind the fantastical stories deliberately written and openly presented as figurative instruction and not literal history.
