Costs of set up / take down

Hi all,

We've got an early morning wedding and as we won't have access to the venue the evening before I'm a bit worried about setting up all the decoration, chairs and whatever else is necessary. Our wedding is still far away (not until June next year) but I'd really like to know what I should think off in terms of costs if I would get someone to do it.
I had also post this on the Greater Vancouver wedding Facebook page, but I just get replies with links to whichever company is helping them or who could help us out. I am not interested in asking someone for a quote, because I'm pretty sure I would end up in their contact list and keep on being recontacted if I wanna hire them and I won't feel good about that (I do understand it divers from venue to venue and definitely divers between cities and provinces, but since it's so far off I'm really just looking for a general idea) Any people that can share how much they're paying for it?

Oh and also (I will also ask my venue of course but I'm leaving it for now since they're pretty bad at getting back to me) is your venue end time including cleaning up? Or do the people just need to be out of it but you can still clean up after? We got our venue to 4 o'clock so I'm really wondering if I have to get everyone out at like 3 or something in order to still clean everything up
