Are you serious? My bid for 20,000 words a week works out a lot cheaper than 40 hours a week and you're still looking at $1000 a month, sorry.
For that, though, you will get exceptional work in a timely manner. All work would be thoroughly researched and I would guarantee a minimum of 20,000 words per week.
If you expect exceptional work with exceptional English skills I would imagine you're going to struggle in that price bracket. If you are struggling and interested then please let me know.
This bid will buy you about 6000 words a week over a month.
Thanks,
Matt
