Activity for Lt

I am having a small church wedding and since hair and makeup are important to me I have been looking into those vendors. But, how do I give them a time I need to be ready by if I don’t have a photographer/video yet and not sure about where I’ll be...

During the trial for hair and makeup do they use the same products and amount as the day of? Is there any difference between the trial and day of? Does hair and makeup work at the same time?

Looking for affordable wedding venues/ restaurants that have private dining that look like RH Rooftop Restaurant aka glass, greenery/flowers, chandeliers? Suggestions? http://www.rh.com/westpalm/restaurant
