Every job is a bit different so we’ll provide quotes on any project but there are certainly types and sizes of jobs:
This might be a letterhead or factsheet with a colour palette, first and following page and two or three text styles, or a presentation with a title slide design and a body content slide. You can expect small jobs like this will cost $110 or less.
This might be a simple report with title page, table of contents, text and table styles and sample layouts, or a presentation with a number of different slide layouts. Something like this might cost up to $300.
A more developed report or complex presentation is going to take longer. It really comes down to how many styles and layouts are needed and how much needs to be editable.
