Hey Gladys, Congrats on your engagement. There are lots of Cabo girls here, so I am sure we can slowly get thru all your questions...
I got married in November and found prices to be pretty good. They started going up again once thanksgiving/christmas/new years hits, then I don't know about the spring, sorry....
We had lots of guests stay in condos and private villas found on ..VRBO® is Vacation Rentals by Owner® Vacation Homes Rentals by Owner which worked out great. Lots of people stayed for $75/night and had a kitchen (another moneysaver). We recommended our guests rent cars. Then they could get to all the wedding events but also go exploring on their own.
If that doesn't sound up your alley, you could also consider an all-inclusive place. Dreams and RIU are most popular for brides.
There is a Catholic church in San Jose. MariaElena got married there so search for her review. I think Pueblo Bonito Sunset Beach has a pretty chapel. I forget the others...
For a bargain WC you could hire Maye ($900+) or for full coordination you could hire Tara, Amy, or Lisa from Fiestas Los Cabos ($3,000?)
Hopefully that is a good start!
