Jacking a door way to install header

I bought a 2 story house a few years ago. There is an 11ft wide doorway on a load bearing wall that doesn't have a proper header. It has sagged about 1 1/8 inch. I need to jack it up. Build some temp walls. Remove the doorway and reinstall with a header. There is a 6x10 girder under the doorway.

I have a few questions. I was going to try to use a 20 ton bottle jack to lift the doorway. I have 2 jack poles as well. Is that jack likely big enough to do this job keeling in mind it is load bearing and a two story house? Also how much can I lift it per day without destroying the closet doorways upstairs that are immediately above it? They are already bound up from the sag. Last thing. I was going to use a double lvl header. Would that be OK or do I need a steel beam?

I've attached a few pictures of the doorway, a pic of the foundation under the doorway, and a picture of the upstairs doors.
