Hi,
I advise you to do marketing of your channel for a long term i.e at-least for a month. Otherwise don't waste money on it as it will not give any significant benefits.
If you want to to google ads for a month time, I can help you for that. I have 12 years of experience in digital marketing and can do wonders for my clients. i joined freelancer recently so dont have many reviews but once you will work with me you will get to know how useful I am when it comes to digital marketing field. Waiting for a positive response from your side.
Regards,
Aman
