How many backlinks per month in SEO package?

SEOs and marketing agency owners, could you please share how many backlinks do you usually create per month for a client who is spending 500 USD per month. What kind of backlinks are these? Business profiles, forums, social media? Do you break down between do-follow and no-follow in report?

If you could also share what deliverables are included in your monthly SEO package, that would be great too. Thanks
