Before you get in touch
GOOD TO KNOW.
Can I bring an unfinished demo?
Yes. Send your current version, references and where you want to take it. You do not need a finished release plan.
How are price and timing agreed?
They depend on the project scope and crew required. We confirm the budget, timing and deliverables before work begins.
What will I receive, and how are revisions handled?
We agree formats, versions and revision scope for your project in advance. Tell us where the result will be used and when you need it.
Does completing the form confirm a booking?
No. The form prepares an enquiry through email or WhatsApp. A booking is confirmed only after we agree it together.
