Your team is maxed out and a client project needs to ship. Book me for a day. I drop into your workflow, your conventions, your repo, and deliver.
Three lines is enough. I'll reply within 24 hours. We'll figure out the target together. The day itself is a collaboration, not a drop-off.

Know exactly what you need in place before day one. Takes 30 minutes to prep, saves hours on the day itself.
I'll send it personally. Fake email = you won't get it.
