What are some good options for veterans seeking venture capital or angel investing?

That really depends on numerous variables. The first questions I have are what phase are you in? Are you trying to raise money or do you have a proof of concept. If raising money you need to have a strong business plan together and likely be more successful getting friends/family first, lines of credit for the business etc.
If you have a proof of concept already done, something that is somewhat ready for market then I would suggest first looking at your local community. Major universities often have an early stage VC arm (I worked at one during my first graduate degree). You can reach out to the university and find out whom to contact; it will take numerous calls.
Second is find VC/Angel investors in your area. Google is your best friend here to cross match names and your area.
Going into the larger middle market means you are past the proof of concept and actually doing sales. This area is more liquid and easier to reach out to once you have things moving.
Make sure you have EVERYTHING lined up before you talk to a VC/Angel. THe questions will be difficult but you need to be prepared as failure to prepare is a huge red flag.
Hope that helps. But if you have more details I can better assist you.
