Tell me what you need. I’ll work out how long it will take and give you a fixed price. If you’re working to a budget, that’s fine, we can work something out. Payment will be half up front and half when it’s finished and you’re happy. If I underestimate how long it will take, that’s my problem, not yours. I’ll finish the work and charge you what we agreed. If I’ve overestimated then I’ll only charge you for the time I took. You’ll see the difference on the final invoice. My minimum charge is for a 1/4 of a day.
