It's easier to get published by an e-press for a lot of reasons.

Whether it's worth it or not is something you'll have to judge for yourself!

$5000 buys you a good deal of promotion if you spend that money wisely -- target readers, rather than booksellers. Build a good website, get a good mailing list going... or don't do anything at all. Self-promotion is important, but if your books suck, nothing is gonna help that.
