Answer 1

Depends only on the customer. Try to charge a couple of thousand for the logo and 500-1000 for every other layout.
Prices in rubles.

Answer 2

the billboard looks like the site header)
But on the topic, the prices are different, evaluate your time spent, and not what you did)

Answer 3

First, the price is negotiated, then the work is done. without a watermark, files are given only after full payment, no matter what the customer hangs (this is so, for the future)
According to the work itself. IMHO:
Billboard? Correctly noted - it looks like a website header, but there is nothing wrong with that)) but the name should be BIGGER, the words should also be larger, otherwise it is simply unreadable.
Business cards - firstly, a BIGGER name, it must be increased by at least 30 percent. Secondly, it is better to do it in a vector (even if the pictures are raster) , in my opinion, prepress is much more convenient, especially with Corel, thirdly , if the drawing or fill is at the edge, then on the layout for printing it should go beyond the edge by 3-5 mm, so that when cutting business cards(which rarely turns out to be perfect, especially for the entire batch) , there were no white stripes between the edge of the picture and the edge of the business card.
"We have everything for your windows" raise a little higher so that there is a little more free space between the inscription and the line, in the list itself, also make the distance between the items a little larger. A plate with contacts, if it’s so impatient to do it, it’s better to make it ... well, xs ... pale pink or something, it’s more appropriate there than yellowish-greenish, it makes sense to repaint the green plate at the bottom of the mb, for example, in blue, which can be taken from the back.
