It's extremely hard to sell something you're not passionate about.

Have you looked into other options, such as selling the company or hiring a sales team? With only a few clients it probably wouldn't be a huge sale, but someone who has connections in the education space could further monetize it, and you'd be delivering a working, proven moneymaker.

A sales team would be riskier, but if you like working on the company and just don't want to deal with sales, you could figure out a way to pay other people to sell to administrators. It would require an upfront investment, but you just have to do the math: "if I hire this person for three months at $5k/month, how many clients would they need to bring in to make it worth doing?"

A salesperson with passion and connections in the space can likely sell far more than you could (given your lack of passion).

The question is: if you could grow your user base without doing the selling yourself, would you want to continue working on this company?

I've started and sold (or folded) several SaaS companies, and I'd be happy to discuss my decision-making process, strategies, and outcomes with you. Just let me know if you'd like to talk.

Good luck!
