what exactly are you trying to do?
Like all of his posts he is trying to find a way to get rich quick, lacks any skills and trying to let others do the work for him.
Well actually you're wrong, you can find a private key or even its range from its public key.
Ok, here is a public key, 130 bytes uncompressed:
04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f
Please prove us all wrong by "finding" the private key for this public key. Until then I would trust the answer of pooya87..
