I am going to build a chamber type vacuum sealer.

Unlike the Food-saver Seal-a-Meal machines that pull a weak vacuum, do
not seal really well and use expensive special bags, a chamber style
has an impulse sealer inside the chamber and the product is bagged,
set inside the chamber, and sealed after you have drawn a vacuum.

What will you use for the self-powered remote control sealer?

Im rather courious how they close the bag from outside the vacuum
chamber once they pump out the air?

What do you think is particularly difficult about that? An electically
operated clamp and a resistance heater would do it. These things have
no problem operating in a vacuum. The control and power wires pass
through vacuum-tight connectors - for instance:
