Of course, this is going to depend on what custom essay writing service you choose to use, and the prices will vary dramatically depending on the quality, the deadline, the academic level, and so on. This makes it hard to pin down an exact average price of what you can expect. However, as a rule of thumb, for a mid-academic level (say Masters) with an average deadline of seven days written to an acceptable Pass quality, you can expect to pay around $15-$25 per page.
