A lot of these types of posts about B2B assume you are selling a product >$1k... there are lots of B2B that are for less than that and so you can't really apply most of these approaches.
If you're selling a B2B product for <$1K, you'll probably need the customer to come to you instead of you reaching out to them. This could be through strong marketing and branding.
I only have experience with >$1K B2B which implied outbound sales (company contacts potential customers).
