Product photoshopped into lifestyle backgrounds & Smart object

Hi,

I need my product photoshopping into backgrounds for my product photos as realistically as possible. These will be 1600 x 1600 pixels PSD's. Please send samples of work where you have photoshopped a product into a scene.

I have attached some photos of the products cut out and have more with different angles to use, whatever one sits best onto the background. It needs to look realistic as these will be used as my product pictures.

I need around 5-10 different background scenes with a black and a brown lap tray in each as the main focus ( if possible both colours in each but okay if not ) and it setting up with a smart object where the white box is inside the frame. So I can add an image on the smart object and it will add the image to the two lap trays then I can choose from each frame depending on the image design.

These are beanbag lap trays which you eat your dinner from on your lap. So ideally need it photoshopping onto images like sofas or chairs, beds and one in a children's room. Some stylish ones would be good.

Thanks,
Danny
