Chetan, happy holidaze to you, too.
Some riggers do operate rotary swagers out of their vans and so they can build up a new rig at the boat (or rather, while in close proximity to the boat). The machines capable of doing standing rigging are not portable. Be sure the swager is easily rated for your size wire and it produces smooth, symetrical swages or you will lose the rating of the wire.
Norseman & Sta-Loc self-installed end terminations are an excellent alternative to rotary swaging end terminations. The initial cost is more but the long-term cost is less.
Nicropress fittings are not intended for rigging, altho' you will see boats using these on occasion. They should be fine for smaller rigging loads (outhaul pennants, lifelines, tack pennants, etc.)
Here's a suggestion for you if/when rotary swaging terminations onto wire: As each swage is finished, have someone ready to take the wire end, invert it (so the termination is 'down', standing part of wire 'up'), and run a heat gun over the last 1/2m (18") of the wire and the entire swage fitting. Get both very hot (gloves help), and then run a stick of beeswax up and down the full length of the heated wire, allowing the wax to soak into the wire strands and slide down to reach the fitting. You will know you are done when the wax stops being pulled into the fitting and pools at the fitting's mouth, then spilling over. That treatment will make water penetration almost impossible inside the swage, which is the primary source of corrosion in a swaged piece of standing rigging. Works a treat.
