Does having pre-published work effect your getting an agent?
*affect*
Agents will be interested in writers with a publication history--so long as the sales are good.
I am currently thinking about publishing some of my work in the form of an E-book. I was also thinking about posting some of my work on my blog.
Ah. You're talking about self-publishing your work and then querying it, and not about having other works already published.
Note that the format of e-book vs. print isn't the issue here: it's the self-publishing that's significant.
If you sell loads of copies of your self-published book (I'm talking tens of thousands of paid-for copies here: the average sales for self publishers are in the low double digits) and build up a huge following on your blog, that might make an agent sit up and take notice. If, however, you don't sell anything and have very few followers, it might well work against you. Publishers tend to prefer new, unpublished works, and might take that lack of sales as an indication that your work has no commercial potential.
I was wondering weather professional editors/agents dislike or steer away from self-published authors.
*whether*
No, they don't. Agents, editors and publishers are interested in good books with strong commercial potential, written by people who behave in a competent, professional manner.
If those books have already been self-published there might be a few problems: for example, publishers will want to edit the book and might not be happy about an unedited, self-published version floating around; and having the book already out there makes it difficult for the publisher to market the book as new, which reduces the publicity options open to both writer and publisher.
In general, self-publishing is not the route to take if you're aiming for a trade deal. Agents and publishers still sign up most new writers from their slush piles: finding a publisher as a result of your self-published success is still a rare thing.
A final note: agents, editors and publishers are put off by books which have lots of clumsy errors in them, like the two homophone substitutions I've highlighted in your post. Such errors suggest that a book is going to require a lot more editing, and the author might find it difficult to participate fully in the editing process.
