Where do i start for creating a bitcoin altcoin? Like for changing block times, names, coin max, etc? I know what i want to change but I don't know where to change the code for the basic things mentioned above.

    You should break this question up into its particular parts. Here's a general primer with max coins bitcoin.stackexchange.com/a/19288/5107 Block times has been answered elsewhere. The variable is called nSpacing or something to that effect. You'll have to be more specific on "names".

    There are hundreds of altcoins. Your altcoins has a 99% chance of failing and if you can't code and can't capitalise your "I"s properly then there is nothing you can add of value to the altcoin economy. Commented Jul 2, 2014 at 9:26

    For the love of God don't bother bringing a clone coin with no innovation. You won't get rich. You're not doing anyone any favours. You missed the boat. The lowest standard for a new coin now assumes some innovation. Once more please don't bother. Commented Jul 3, 2014 at 11:45

This post on bitcointalk is a good starting point.

The basic idea is to:

  1. fork an existing coin
  2. Customize some values (block reward, block time, hash algorithm, etc.)
  3. Boot strap the coin by mining then encoding some checkpoints.

If you're not necessarily too technical and depending on your goal, you may want to look for a service that can run your altcoin for you and provide higher level APIs with it. For example: http://www.blockcypher.com.
