Don't be disheartened. Right now, not a lot of companies are hiring. I spend 10 years in sales/sales management in the pharmaceutical and medical device industries and it is hard to break into them. Took me a year of applications and interviews.
Companies are always looking for good salespeople. In addition to medical device and biotech, look into lab service providers (Labcorp, etc.), other medical supplies (think of everything that goes into a hospital - surgical supplies, sterilization/disinfecting supplies, etc.), agricultural products (fertilizers, etc.), food products/ingredients/manufacturers, and others where having a base knowledge of biology could come in handy. A guy I used to manage just got hired as an inside sales rep at Exact Sciences, and I don't think he had a lot of sales or biotech experience. Inside sales could be an opportunity to work from home.
If you have a good relationship with your doctor/dentist/etc, ask the people in their office to recommend any companies that supply products and services to them.
