Before I was able to get a publisher for my collection, I had over 100 shorts in print. The current collection contains 19 previously-published stories (including those nominated for prizes) and 2 new stories.
If you don't have a name or a following, you need to have some publishing credits. Even then, a collection is a hard sell to many publishers because it is a hard sell on the shelves.
Yes, there is the straight-to-ebook route, but again unless you have a customer base, you will be asking yourself where are the buyers?
Best of luck. Seeing the stories in print first time around was a thrill - not to mention getting paid - but seeing them in a collection is also a thrill, although the getting paid part is not exactly NY Times bestseller stuff!
