How do you estimate that I should pay maximally to a professional chess writers for one article? It is important to me to know that.
Grandmaster level writing is an expert issue. You will pay realistically. What you want to pay may not be realistic.
Your budget does not dictate what market prices are. The market dictates what your budget should be.
I find all over the internet people write on all subject for 5-10$ per article.What can I expect from that?
Pay and find out. They will not be grandmaster level articles. They will be generic scrapes of basics, just like all the other five dollar articles. Anyone who wants a site to rival yours can have one for a few bucks within days after you start yours.
Anyway I am open to all options...
No, you are not. Or there wouldn't be a budget problem -- you would already have your articles and therefore have no need to post here.
We need a page on what budgets really are.
...A budget is not what you prefer to pay.
...Budgets are set through research. They are not picked out of thin air with little to no knowledge of prices or value.
...Various laws of Physics and mathematics are fixed. And we still manage to modify them upon deeper investigation and discovery. Budgets are infinitely malleable.
...Just about everything currently out of your price range can become affordable through budgeting. You set aside an amount until it becomes affordable, you buy. Or you find another income source. Or you sell something. Then you buy. Simple.
....Budgets are made by humans. Budget can and are changed all the time -- every day. The word budget does not in any way shape or form mean the budgeter does not have any more money to spend. In fact, the amount they tell you may only be a fraction of what the company has already budgeted for the very purpose you're discussing -- they just won't tell you that at the beginning.
Most of the people who have cars don't have the cash sitting in their pocket to buy a car ...yet they still drive. Figure that out, and you'll be on the way to discovering what the word budget actually means.
