Open the lowest level store subscription, and then go into the settings and place your new store on vacation mode.
You won't lose any of your listings, people will still see them in the searches, but they won't be able to purchase anything until you take the store out of the Vacation Setting.
It'll cost you about $25 for the month, but it won't cost you any lost sales, or mess up your standing from not being able to ship stuff on time.
It will give you the option of have 5x the number of listings too, from 50 to 250 free.
That way you can take all the time you need and you don't have to worry about ebay until you come back.
And, you won't lose any of your work.
After you come back, you can just cancel the store subscription if you don't want it.
