Wordpress theme customization

I have purchased a WP theme and need to customize it to my needs. - Design and apply site-logo - Change few images from the original template to my own images - Get screenshots from external site and software and add them to the theme Only serious workers with great design skills. Please do not bid if you do not have at least 5 feedbacks/ratings on this exact subject - logo and image design. * Designer agree not to publish my work in his portfolio or use it as reference. * Designer will send the images along with their originals (PSD or equivalent)
