Here's my advice, read through the forum and see what you like. The WAYWRN thread will be your best friend. If you see a picture and think "wow that looks really good" write down what the person is wearing, i.e. suit color, shirt color, tie color, etc. Then every night or every morning look though eBay for the items within your budget. You'll be surprised how quickly you come up with outfit ideas. Some advice I've learned over the years is to take EVERY suit to the tailor. Make your tailor your best friend. If you have $500 to spend on a suit buy a $400 suit and spend $100 tailoring. I can tell by looking at you that you'll look good wearing a staple color item and using accessories to make it your own. Think blue suit with a crazy pocket square. Again just looking at pictures on here will tell you what combinations work.
Now to save you some money.
A good pair of shoes will last you a lifetime so spend the money. Stay away from anything you saw your dad wear. Buy wingtips, oxfords, cap toes.
There's a lot of vendors that sell on Styleforum who can hook you up with ties, pocket squares, belts etc. Again, spend the money, the stuff is worth it.
(Make sure you buy two button)
Suit supply is very good to buy new, harder to find used.
Other than that see who makes the ones you like in the WAYWRN thread and search eBay.
Now since you wanted pictures;
The top one is an example of a classic look, the bottom two are Harvey Specter from the show Suits, another great source of inspiration.
