Your friend cannot count; only close family members can be considered as ties to Saskatchewan.
There is no minimum 400 CRS score requirement for Saskatchewan. But your Express Entry profile must be valid. If you say you're in the pool, then I assume your profile valid.
Your NOC must be in the in-demand list, see Appendix A in the PDF:

But they have their own grading system and you must get at least 60 points. You can do the pre-screening on their site:
