Hi,
You are looking a freelancer who are an expert in youtube marketing to increase the views and subscribers to a youtube channel.
I hope ur are right place and the following way I can increase your viewers and subscribe of ur channel will increase dramatically.
1st step: You have arranged ur channel so viewers are pleased to see it .
2nd step: Every videos title, description and tag has to set and put such key word by search of key word tools. (It is on page optimization)
3rd step: Invisible optimization (For that have to inspire people to like, share, subscribe by annotation, cards, Subtitle & CC, have to upload HD video, high quality videos, set good thumbnail, recent topic videos etc.).
4th step: Link building in different blog, facebook, youtube, newspaper, forums etc sites. Off page optimization.
All are white hat method. If you follow these thing your channel in 1-2 months will get more viewers.
Thanks
