Robert, it really depends on the application you have in mind, and the industry to which you want to evangelize. My team offers a chance to have your own monthly column in Forbes. We should talk.

Robert - Depends on what industry you are looking at, there are various options like Fiverr, Upwork and several other freelance options.
I had the same question, so I researched dozens and dozens of sites and put the best three on my site.
There are plenty of websites offering writing services but some of them are too expensive or bad quality. Of course, the price depends on the level of work and urgency. If you want to get a good quality essay, you should pay attention to Paperhelp. I have ordered lots of papers there and every time I was happy with the result.
Depends how much you want to pay for text. Fees are from 0.2$ per 100 words up to 8$ per 100 words.
This is overall which I pay now for writing services.
