Ask HN: Potential customer asked about corporate accounts. What to do?

I started a "startup" 3 months ago and I've been plugging away at coding and marketing it on the side. I've got a couple of paying customers but things are still pretty raw.

Today a person reached out to me to ask who to contact about corporate accounts. I feel like I need to take advantage of this small opportunity but I'm not really sure how.

It would take me 2 to 4 weeks to have the app ready for enterprise use (as I imagine it) at even the most basic level.

What's my play?
