Professional high quality photoshop of bedding colours

We are a silk bedding and apparel company due to launch in a month's time and our photoshoot has been paused due to the lockdown. Therefore we are looking for a photoshop expert to create a high-quality image mask that we can use for the product photos on our website.

We will provide you with an image of a bed (below is a sample but it's not the final one), with two pillowcases, and with 4 pillowcases arranged. We require the bed to turned into an image mask, so that the colour i transparent but the folds and shadows are preserved, so that we can add a silk colour layer to the image in photoshop and it'll look natural in that colour.
The duvet cover, flat sheet, bed sheet should be on separate layers, as well as the each pillowcase on a separate layer. So we can put different colours on each layer, to make arrange the bed in different combinations.

I've attached an example of a cushion using this layer mask that can have any colour or image applied to it in photoshop as a layer mask and it looks real.

Milestones:
1. Apply and attach some previous photoshop work
2. Should you be shortlisted we will transfer £10 for you to work on a demo. Change the colour of one of the pillowcases.
What we are looking for is the image to look natural.
3. Once you are awarded the job, we will provide you with the colours, and you will create the image mask and show examples of the various colours below + ivory.
We will work with you for editing about 20 pictures with different permutation combinations.
