Site to source hashtags from

Is there a website that can help me list hashtags based on their competitiveness? For example, I only want to use low-volume hashtags in the sizes of 50.000-200.000, but finding these manually takes a lot of work. Which sites and resources can I use to help me in finding appropriate hashtags in appropriate sizes?

You can basically look for these on Google. But as for me, I usually use top-hashtags and ritetag -Micah
