Hi,
dear i know about 3rd party plugin but it has just uploading option at the time of checkout while I'm looking that user not only upload task but also he fill a comprehensive form then when admin conform and upload user's given task so user will be able to checkout and download his uploaded job,
i can describe you as:
1) user register
2) he fill a from which included his requirements and also attached an image.
3) admin get inquiry and redesign and upload user's task as he describe in form.
4) now user pay his payment via any payment method and download it.
