Hi, I a professional writer and article spinner. I also use BestSpinner for spinning. I have done many projects to the complete satisfaction of my customer. Please see PMB for the sample of projects done.
I assume that the base article had 500 words. After spinning 4 times at sentence level, it ha become 2000 words. After I do word level spinning, you will get the final article which will be around 4000 words. If my assumptions are right, my bid for 1 article is $30 and for 5 spinning 5 articles is $135. Please interact further any clarifications. Regards - lmvram
