Does somebody know about articles at educational websites?

I would invest in Instagram advertising. Your target market uses Instagram heavily, so this will be an effective use of advertising dollars. Any kind of social media advertising will get you exposure with these age groups. You might set up a twitter account if you haven't already. You can promote your tweets and get your site out there. Maybe offer some kind of promotion for retweets, or special service or discounts through tweets that only your followers get or are eligible for. If you want an example- @HiddenCash on twitter. Hidden cash gains followers by tweeting out clues to where the cash is hidden in various locations. Best of luck to you!

If I was you I would contact the guys from Altschool that just started one, and can probably help you with it. Contact on Twitter @rubenharris he can probably help you.

Investors do not fund ideas. You must prove significant market interest in a product. Statistics that highlight potential don't translate into your product's revenue. Investors want to see how they will get a return on their investment. As for a business plan, be mindful that this is an investment document that in addition to a narrative must contain solid CPA-driven financials. Investors also want to see that you have put more than thought into a start-up before they invest. Need a way forward? I'm happy to assist.

Are you pursuing a for-profit or non-profit model for your school? Do you have an education background? Are you certified to run Montessori school? Initial recommendations: •Investigate the California Department of Education requirements for operating an educational institution. •Investigate the requirements for the two accrediting bodies for Montessori: AMS <http://amshq.org/School-Resources/AMS-School-Accreditation> and AMI <http://amiusa.org/>. While not required, private schools are reputation-based and accreditation plays into your brand equity. •Investigate the requirements for the regional independent school accrediting body. While not required, many Montessori schools struggle to keep enrollment through elementary and middle school as parents expectations shift to college preparation, which Montessori does not have strong brand recognition for, and adopt a academic rigor / progressive education model of education accredited by a regional independent schools association for credibility. While starting with kindergarten frees you from the state early childhood childcare regulations, which can be onerous, it also cuts off your funnel. As a school brand, Montessori is precisely strongest at the very early ages, so you may have a challenge attracting families who already started their child with a Montessori school that has a preschool. Many Montessori school start with 18-month infant & parent programs. Best regards, Keith Gillette

Cost of customer acquisition will depend a lot on what type of course you're looking to sell and your target audience. No one will be able to give you a straight up answer here. If you're able to provide more details, I could give some more nuanced advice :)
