Ask HN: Sponsorship/Advertising for a B2B Infosec Product?

My microISV will soon be ready to launch a new infosec product, which is targeted at businesses (it will not be sold to consumers). I'm trying to find sponsorship or advertising opportunities to help get the word out, but as a microISV funding might be an issue. For example, I thought about sponsoring Troy Hunt's blog... but he wants $4,000 USD - per week! Anyone got any ideas on how I can effectively sponsor/advertise a B2B infosec product? Total budget is $2,000 for 1-2 months.
