Photography Scheduling help

Since I am beginning to make appts with photographers, I was wondering a few things.

If I am getting ready at home and want pictures there, how early would you appear at my house.

How much time should I allocate to take pictures after the ceremony. My church has a nice garden area not large but pretty that we could use. I do not want to go anywhere else to take outside pix.

We are trying to decide when we should have our ceremony, which my priest has noted 5:00 but we can do it earlier if we want. My church only does one wedding on Fridays. My reception hall says we should be there 2 hrs before the cocktail hour (7:30) for pix on their grounds. Which I find to be too much time. I am having the reception at Chateau Briand.
I think it shouldn't be no more than 1 hr.
Given that, say our ceremony begins at 5:00 pm and we are done by 5:30, with pix, releasing of the doves would be around 6:00 pm and us jumping in the limo to head to the reception that is 15 minutes away and begin taking pix there we should be done by 7:30.
Would the 1/2 hr for the pix and everything else be enough at the church?
Thanks for the help.

Depends on your photographer. Everyone works differently, and some DO want 2 hours for portraits. We work pretty quickly and can do all the posed groups in 15 minutes to 1/2 hr and like to start with getting ready an hour before leaving (before you put the dress on)

(This is meant as information and NOT pushing my services )

I was thinking that an hour would be sufficient at my house while I got ready. Two hours is too much time. But maybe since the girls would be lingering in the house, those would be some amazing shots that I would not be in it for me to see.

Thanks Mark and no worries on pushing your services.
