I need an existing drawing re-drawn with an additional image

We have an image we want re-drawing with our logos/information on it, A4 Portrait, and with an additional drawing adding to it. Just to clarify, we need it re-done and not just copied.

The additional drawing to add to the Carbon Monoxide section is for a CO2 alarm near a gas cooker hob. The legislation is ""A CO alarm near a gas hob should be placed 1–3 metres horizontally from the hob, situated at head height on a wall, or on the ceiling at least 300mm from walls. It must be placed above door/window level (15–30cm below the ceiling) to avoid false alarms from cooking fumes."" So the new drawing must show this some how.

The layout on the A4 page must be really clear and simple to understand. The format and colours should be as at www.propertymonsters.co.uk
