I have no suggestions where to find people to talk to (that really depends on your field). But on the topic of how to talk to people, I really want to recommend the book by Dale Carnegie 'How to make friends and influence people'. Ignore the corny title and read it. This book has changed how I talk to people. The biggest takeaway for me from that book was that people love to talk about themselves. Make the conversation about them; focus on their situation instead of on your product.
