The problem of using your service to send a submission to HN is that the users here will notice the pattern and flag them as spam, the mod will notice the pattern and will ban the site and the accounts. So ... reduce the number of sites to 99 and just skip HN.
My recommendations to your potential clients is to post it here themselves. If the post get any traction and feedback it's important that the owner of the site can reply and interact.
