You have a B2B product. Business rarely look for new stuff, you have to shove it down their throat. So just search for about 100 physiotherapy stations near to you and then email them a short email, asking them if you can actually email them with the product information.

A personalised email for EACH site individually. Hire someone to do this if neccessary. Track your replies. If nobody replies, then you don't have a product. Otherwise, lead them through it.

The more emails you exchange with a customer, the more likely he is to buy! B2B is all about communicating with the customer, making him feel safe with you, like you are a partner taking care of a small part of his business.

Always end every email with a hook that will make him reply to you.

Press-Release, Relevant Blogs and so on are NOT going to make you customers. You have to reach out personally! Your market is too small, too in-cohesive and too static for anything other than aggressive personal approaching your customers to work.

I've done years of these types of sales, and I hate it with a passion. If you don't like writing emails to people then figure out how to get someone else to do it for you.
