Market valuation for SMSF

My SMSF auditor has advised that I need to provide 'a market valuation report for the shares at 30 June 2022 issued by an independent qualified valuer.'

Has anyone else been through this process? Is there some way shareholders can share the cost of such a report? I'm imagining something similar to the way property inspection reports are carried out once, then all potential buyers can download a copy of the same report for a discounted price.

Or failing any sharing arrangement please let me know if you have any recommendations for a valuer.
