The more milk you remove from the breast, the more you make ... Remember the ABA is always there with advice for all things feeding-related - including info on expressing and storing expressed milk.
yeah, that!!

and as far as storage goes, just store them in pargels that are the right size for her feeds. and you can store them for a while, to build up a bit of a bank, so the feed that your DH is doing, you can do a full express and store it up.

DH will no doubt *love* being involved in the process
