Consultancy for strawberry growers is always tailor made. There is no standard plant, there are no standard circumstances, there are no standard growers. Everything is different. 
Also the way of consultancy is different. Consultancy and its way depend for more then 50% on you as grower. Who are you in live, how do you want to run your company and how do you see your future.  What is your view for your crops, for your own development, for your employees, for your market. 
As that differs, consultancy differs also. 
The connecting line for all the growers i visit is be a sparring partner, think with you. 

Although there are much different ways of consultancy, several products are quite standardized. Here below you see a list with products and a price indication.
