"look forward to hear/hearing from you soon and receive/receiving"?

[Odessa Dawn]

1. "I look forward to hear from you soon and receive your updated CV."
2. I look forward to hearing from you soon and receive your updated CV.
3. I look forward to hearing from you soon and receiving your updated CV.

Are the first and (the) third ones grammatical, please?

Only the third is grammatical.

We always follow "I look forward to" with the -ing form.

Only #3 is correct.
