Looking for the right suit for Cabo Pulmo 10/31

[House Gecko]

I am looking for a exposure suit for Cabo Pulmo during the week of Halloween. I am a big guy 6'4" 250lbs and I often have trouble finding things that fit me. It is my thought to bring my own suit to avoid ending up not being able to find something to rent that fits me. The problem is I do not know what the right suit for Cabo Pulmo is at the end of October.

Some of the suggestions I have got from the local dive shops in the San Francisco Bay area are:
3/2mm full suit
3mm short suit
2mm short suit
dive skin
short suit + Dive skin

Any suggestions would be greatly appreciated.
