I don't want to limit your creativity so these articles should not be cut at 500,700, 1100 words. Use as much characters as you want to finish your article properly giving the full picture about the topic and if you undercalculated your price you will get an extra payment as a bonus.
I'm really picky about the quality so please send me a sample project you have done in the past or I will not read your bid.
