Cost us £45 to do ours. Antifoul £35, rollers and paint tray £10. Chuck on some scruffy clothes and paint away. Only took about half hour per coat with the two of us doing it. Never understood people paying for it doing, granted if its flaky and needs a lot of prep work maybe.....
It was pretty scruffy in fairness, and there wasn't a bootstripe. The paint alone was £130, so there was no way it was going to be as cheap as yours, you lucky thing! I have spare paint for next year though!
