Creative deal terms with seller stuck on price?

Have been in discussions with a seller for several months and negotiations have recently come to a standstill. We have built a really good relationship to this point and both sides want to move forward but we are not aligned on one item - price (not a surprise). The seller has chosen not to use a broker and have not gotten a 3rd party valuation of the business. This seller has also shared that they have had several failed attempts at selling the business because of price. Looking to the SF community for any ideas or creative ways to negotiate terms to get around price to continue moving forward with this seller. Happy to connect with anyone directly to share more details and potentially use to help get the deal done - please DM me if interested.
