ebay and amazon

Bulk setup and upload to ecommerce marketplaces (Ebay & Amazon): Background: I am looking for someone with successful experience with the setup and upload of bulk listings to ebay and amazon. I have been using ebay for several months and just started with amazon this week. I have uploaded roughly 80 items to ebay and a few to amazon so far. I have done this one listing at a time. Unfortunately, time is not on my side as I am juggling being a father (just had a son on 10/31/16), husband and small business owner. At this time, I am the only one running the business. I have inventory sitting in boxes which I haven't gotten to due to time restraints (not a good business practice). Details: I have several hundred items in inventory on a google spreadsheet which I can convert and download in different versions. I do not use microsoft office but do use open office. My typical business practice is to inspect and receive items as they come in, I enter certain details of each item into my spreadsheet while taking several pictures of each and then uploading to a corresponding google drive folder. I am open to using other means for photo storage if it will be easier for uploading. Needs: This person shall be knowledgeable with this type of uploading to both amazon and ebay. This person shall be able to provide direction in case you need more information or information in a different layout from me. I will also need some examples of bulk uploading you have done to these marketplaces in the past. Potential: The reason I am asking for bulk uploading is so I can get caught up with the listing of all of my inventory items. Moving forward, if the relationship works for both parties, I would like for this person to upload listings either as received or weekly/bi-weekly in bulk. In addition, I am working on setting up an ecommerce store where work may be needed too.
