Is there a good site for a free load calculation for a church with a 3 phase service? :?

Thanks guys. Been a long time since I did one. hmy:

What I came up with, but seems high!
2,000 sq.ft. @ 1 volt-amp = 2,000 @ 125% = 2,500
sign = 1,200 = 1,200
receptacles 15@ 180 = 2,700 = 2,700

non-dwelling demand first 10kVa @ 100% = 6,400

fixed electric heating 1 @ 15,000
1 @ 10,000 = 25,000

total = 31,400

31,400 / 240 * 1.732 = 226.6 amps :?
