Seeking the Best Sourcing Services for Educational Staffing

I recently received approval to explore additional sourcing methods, provided I can justify the costs involved.

At present, I’m primarily utilizing Indeed Smart Sourcing and LinkedIn Recruiter. However, Indeed’s outreach is quite restricted due to the limit of just 30 contacts, and while LinkedIn Recruiter offers more InMails, I haven’t seen much success there compared to what I achieve through Indeed and our ATS. My main request is for Indeed Premium, which would grant me 70 extra contacts along with other valuable features, although it comes at more than double the expense.

I’m looking for recommendations on tools that offer a strong return on investment for sourcing educational staff. If you have any creative sourcing strategies or reliable paid services, I’d love to hear your insights. Is ZipRecruiter worth the investment? Has anyone had experience with Teacher-Teacher or Smartspring? I’m also curious about AI-powered services, as long as they adhere to ethical standards for corporate use. Thank you!
