Budget: 27000 UAH Deadline: 60 days
Hello, Ruslan! I just couldn't pass by your task!
You described the task and your requirements very well.
I have experience in editing and layout. I work in Adobe InDesign.
However, your conditions resemble slavery rather than work for a professional who respects themselves and their time (and that is exactly the kind of performer you want to see).
First — these are the deadlines. For such a large volume (1300 pages), 20 days is very little even for proofreading and editing, not to mention design and layout. The real deadlines are twice or even three times longer.
Second — the price. Are you seriously offering people to work for 11 UAH/page?
The cost of proofreading and editing on the market is about 30 UAH/page, plus the cost of design and layout — about 50 UAH/page.
In total: the total cost for your volume of material is at least 104,000 UAH. And this is without considering the design of the cover and diagrams (if they need to be drawn).
Now put yourself in the shoes of a person who would be offered work under such conditions. Honestly, would you work?
