This is something I've always wondered. My first year betting, I had a bankroll of $600, all in BOS, and bet $10-$20 a play. I remember calling in my first $100 bet, and I was nervous. I thought, "wow, I'm a big bettor now."
I really don't know what the average bet would be at a sportsbook. I remember hearing on a Las Vegas radio show that the average bet at Leroy's was $39.

When I started which was like 3 years ago I bet $10 a play for the most part. Now I bet $500 a game usually and sometimes $1000 a game if I feel confident about the game. Like today I got $1000 on the Nuggets -8.5. Pretty sure Nuggets win this one quite comfortably. 
This is probably who could answer this the best.
Not sure most understood the question: Basically what amount bet by a player on a game starts to catch the eye of the book that this bettor is an above average (bet size wise) bettor?
My answer would be $500 a bet at a big book and 1k a bet at larger books and the books would probably look at you with more of an interest.
