Regex, Making A Basic Title

Question

I am currently using Regex and I have absolutely no idea how to. I got somewhere with the help of msdn, but not far enough:

So below I copied and pasted Regex code that I want to include with another rule I need. This code below does not allow special characters as well as numbers in the field:

[RegularExpression(@"^[a-zA-Z''-'\s]{1,40}$", ErrorMessage = 
        "Numbers and special characters are not allowed in the Title.")]

I need this as well as a restriction on using capital letters after every space.

Example: Every Day I Learn Something New <--Correct
but not: Every day i learn something new. <--Incorrect

Just like making a title for an article.

If you can help out an uneducated Regex coder that would be much appreciated

Cheers

FYI, some of us have lowercase words as part of our names.. Example: http://en.wikipedia.org/wiki/Alexander_von_Humboldt - also, movie/book titles will often have lowercased 'of', 'a', etc. — Blorgbeard, Jan 30 '14 at 00:09
mmm, thanks for the insight. I wonder if that would be an issue for my client. I guess maybe leaving that tad-bit out would be more beneficial then not. — 1011 1110, Jan 30 '14 at 00:17

This question describes how to do negative matches. For your case, you could also require that string match @"^((?!\s[a-z]).)*$".
