In addition, I will leave a thumbs up "like" and a relevant comment. I can also type in whatever comment you choose if you send me custom comments. I do this from my PERSONAL account that has my profile pic and banner. Everything is done by me and does not violate any rules.
Finally, I will share 10 of your videos on twitter to my followers -
I have over 20K. As a bonus for new clients, I WILL SUBSCRIBE to your channel and NEVER UNSUBSCRIBE. Note, I only have my one account so if you have ordered from me before I can't subscribe again. Ask if you have any questions. I do not promise your video to go viral but this type of promotion combined with quality content can certainly help get your video noticed.
