Good luck with your service but I'd like to warn you that there the prices are high, realy high considering you can just traffic exchange 10 upvotes on free sites already
Prices are reasonable as the quality is not that good when you get up votes through exchanges upon googling such websites over the internet . If you need quality you will have to spend more else you do not get what you need . If I am not wrong, then by quality he means that someone interested in that topic would up vote and he would have a high amount of karma as well .
