Payment is always variable and negotiable - I am willing to accept new prices, and change my price based on my competitors. If you believe that I have submitted an unfair price for a proposal, please let me know so that I may fix it to ensure a better experience.
For editing jobs, I prefer to receive payment after the first edited draft is submitted, but am willing to receive payment after the project is complete for clients who have worked with others on Elance successfully. For basic, non-heavy editing, I ask to be payed $3.75 per 1,000 words, which amounts to about $7.50/hr.
I always ask to receive payment only after I have submitted the finished content for jobs that involve writing new material. For writing jobs, I ask to be payed $8 per 500 words, which is about $8/hr. For ghostwriting, I charge up to $10 per 500 words, and more complicated jobs can cost more.
These prices are well below the industry standard, for which pricing estimates can be found at http://www.the-efa.org/res/rates.php. For recurring clients or in the case of larger jobs, I am willing to decrease my rates further upon client contact.
