Wildflower Meadow Research

I want to develop a wildflower meadow on an area of land

I need to find out about the different types of 'wildflower meadow' available and how they can be 'comercialised' ie How can the seeds be harvested for sale (its quite a large area of land)

and I need to find out a list of companies that can 'plant' the meadow and potentially manage it and harvest the seeds

Could it be commercialised by having 'tourists'/people visit the site for education/something to do where they would learn about wildflower meadows etc

Please give me your best price
