electric reel is an important essential (and expensive) feature. It costs around 7 or 8oo dollars. Need the hose and gun. Likewise the motor, gear reduction and pump will cost, 1000 to 2000. You need a filter, a pressure regulator valve and pressure gauge, a few hoses, some wire to power the reel. Plastic tank and a few items of hardware are fairly cheap.
Please don't become a lowballer and undercut any of us, OK?
