Recently purchased property in Amherst Township with 70-80 blueberry bushes, neglected past 15-20 yrs.  Many >15' high.  Have started cutting out saplings and dead branches, but need advice re: pruning. 

Thank you for your question. This service does not provide onsite review. You may want to call you local county extension office to see if they have resources or options available for direct assistance. It looks like you are in Lorain County, and you can see their Extension office website and contact information here: https://ohioline.osu.edu/factsheet/hyg-1430

To try to get you started, here is a resource sheet on pruning blueberry bushes in the garden: Pruning Blueberry Bushes in the Home Garden

This is another resource focused specifically on renovating/revitalizing old blueberry bushes that may be additionally helpful: Revitalize Blueberries

I hope this information can help you get on your way to productive blueberries.
