3d rendering and photo manipulation -- 2

Paving stones 3d rendering and placement in stock photos Looking for a highly skilled 3d designer and photoshop expert who could help with our project. We need to show our paving stones in different environments. For this we will use stock photos as background image, where our product should be added to look 100% realistic. These final images will be used online and in print materials also. The process would be: we deliver the size and and a real photo + texture/pattern image for each pavement tile. Each tile should be created in 3d. A large surface should be created of these tiles. The render, final image should be added into the stock photo. Adjusting lights, shadows and fine tune. For some products we have multiple patterns/colors, this means the pattern needs to be updated and replace it in the stock photo. We have about 20 different products and with different colors we have about 50 in total. What I experct to receive: - 3d tile source file - tile png file - hi-quality photos with the new tile surface I will provide the following: -hi-quality top view photo with the product view (pattern) -measurements -a real close-up photo of the actual product -hi-quality stock photo for each product I’m sending attached a few final examples. Please provide an example work where you did the same process so we can see the quality you can deliver. We will need 2 prices: - for creating one product and adding it into the background - for updating the pattern and replacing in the background pic.
