Bathroom mould treatment & repaint

Small bathroom, around 3–4 m², with significant mould on the ceiling and walls, along with peeling paint. I am looking for someone to carry out a proper repair job, with labour and materials included. The work would involve mould removal and treatment, scraping back all loose paint, applying anti-mould treatment, primer/stain block, filling and sanding where needed, and repainting with suitable bathroom anti-mould paint. Please also protect tiles and fittings and leave the area clean afterwards. I am looking for a thorough and lasting job rather than a quick paint-over, so please only quote if you can prepare the surfaces properly to help reduce the risk of the mould returning. When replying, please confirm your total price including labour and materials, the products you intend to use, and roughly how long the job will take. Thank you.
