Hi there, I need someone to courier a box (containing flyers and merch) from my office to another business which is an 18 min drive away in London. Both pickup and delivery are in central london (near the city) It weighs roughly 5kg (super small) (Rough estiamte). Should be a quick job! Pickup must be Thursday 8th morning and delivery MUST be by 10am (by 9am would be best)
