There are many different kinds of investment that you might be looking for. I am afraid you will need to provide further details about your startup's niche, your investment goals, etc. before recommending any particular path. There are angel investors, there are VCs, etc. and also incubators / accelerators depending on what your business is and at which stage it is. Be sure to have a well-researched estimate of how much money you need to raise. I would be happy to discuss the possible options for you over a call.

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.

Start with friends and neighbors while looking for other sources. But in the end you will probably be happy if you don't have to get too many outside investors.

Take the first steps above, work your ass off, build passion and doors will open.

Best of Luck,

I will be glad to help as my time permits.

I have always thought of company investors the way boards at non-profits think of their board members with "The 3 Ws". Those 3 Ws being:
-Wisdom
-Work
-Wealth

Depending on how far along your startup is your company might need board members to have one, two or three of these W's. But any non profit and startup will tell you if the person has enough of wealth you're willing to make compromises on their wisdom and the work with which they can help you
