How can I have a federal and state felony sealed or/and expunged?

Unfortunately, under the current state of the law, one can NOT expunge a Federal felony conviction.

Only a few types of felony convictions are eligible for expungement, and only after 20 years of good behavior (no other misdemeanor or felony convictions during that 20-year period). The felonies that are eligible for expungement in Missouri are 1) passing a bad check, 2) fraudulently stopping payment on a check, or 3) fraudulent use of a debit or credit card device. If your felony conviction is one that is eligible, you can file a petition for expungement in court or hire an attorney to handle it for you.
