If your project is new to me then I will be needing minimum hiring term to be one week (5 days). In a couple of days I will be able to tell you how many days I might need. If you have worked with me before then and I know the project, it is one hour.
What you can hire me for?
You can hire me for 400$ per day or 100$ per hour capped at 400$ per day.
If signed Non-Disclosure Agreement, charges are 50% extra – that would be 600$ per day or 150$ per hour capped at 600$ per day.
