Cut contours of 240 basketball images

We are a basketball federation and received pictures in different sizes, resolutions, poses and backgrounds. The objective is the following for each image: 1) Crop the picture to the size of 150 x 200 pixels so that the head and torso of the player is visible 2) Remove background to make it transparent 3) Put small watermark stating #weareswissbasketball on bottom right with a transparency level that make the writing almost invisible 4) Save the file under the original name and suffix "_HS" as .png (with 150dpi for web use) Pictures that do not match the minimum standards, please reject immediately. We have added a series of pictures so that you can size the project. We will reject all quotations that do not reference clearly to the work here immediately and without further consideration. Thanks for bidding!
