Home-based businesses like ebay are done in either a room or if things get crowded, in a garage or basement. A 200 square foot space is a good way for you to start rolling. It is important that you organize the place and make it like a real ebay store. Be clever when designing a garage space so you’ll keep enough of the garage door area clear so that you can open it and easily move parcels in and out when the delivery folks arrive. It would be practical to make your own shelves. Consider using tall shelves to scrounge as much vertical storage space as you can. Build a shipping table which needs to be a little lower than a regular workbench or desk as most shippers prefer this. You can visit the UPS facility shipping table if you want to make sure of the height for your shipping table. Provide a desk for photo editing and somewhere you can do your photo editing. A Photo table is very important. It can be at least four feet wide. Reserve some sturdy shelves empty store space and for oversized items. Lastly, install smoke detector, extinguisher, heater and air conditioner if necessary.
