Short Code for IG SMS Marketing?

Good Morning everybody or night wherever you are.

I am currently heavily into scraping Data off of Instagram and using it to sent SMS to.
This went well for about 2 weeks than i ran into delivery problems since i started sending 15K+ SMS everyday.

Long Story Short:
Are there any services left that provide Shared short code numbers in the US?
Currently not so attracted to rent one alone since they are 1K+ per Month (Without Setup Fee) and most of the time you have to rent multiple. (3+)

I’d be interested in pitching in for an SMS short code please DM me your telegram if interested
