Product input for website

I am seeking a freelancer to help with product input for my website. Specifically, I need help inputting digital products into an efficient format that can be used by my website. I am open to suggestions for what the format should be; I do not have a template or a specific format in mind. I have a large number of products that need to be uploaded, more than 50. I am looking for someone with experience in product input, who is reliable, organized and detail-oriented. The project must be completed in an efficient manner and I expect a high quality of output. If you think you are the right person for this job, then please apply. Thank you.
