Hi, you want a website from PSD to wordpress based on an existing theme? That means basically working with the theme, or you want a custom theme developed? How quick, depends on your psd, and on the functioalities but 1 - 3 weeks tops. I can make everything manual, but that would be almost impossible for you to change the content and manage the website by yourself, so a composer to be used is the best choice. I'm a licensed full stack web developer and designer. I'm interested in your project, please feel free to check my clients reviews, my profile, my portfolio and if you are interested too, we can discuss more details. Thank you very much, Andrew.
