Wow, this is a really broad questions. Is this your first funding round? A seed round? A series A? do you have revenues? Do you have a product?

Some very general points:

1. Decide if you want just money or 'smart' money i.e. an investor who can contribute more than just cash.

2. Can you raise at least 50% of it from your own network? If so you might consider Crowdfunding.

3. Do you have a lead investor? even if they are investing a minority of the round, this will make it easier to find other investors.

If you can give more information, I will be able to help further.
