Unfortunately I don't as Youtube isn't on my plate and never has been but I know that YT and Spotify are hard to get quality services these days.
If you are super serious then I'd consider creating your own bot for Youtube and creating your own views.
The custom bot wouldn't cost you much and
@Veil123 can help you with that, but good-quality proxies can definitely set you back with "some" for thousands of accounts. If you are wise you can resell the service and cut your costs but you still need some upfront money.. I don't know it's just food for thought if you are seriously interested, you should consider this because dropping tons of Youtube accounts under your own bot is not that big of an operation if you really think about it, but Veil can give you a more definite answer on that.
