Free email marketing

I would like to start an email campaign for my website and found theres plenty of legitimate email companies but none of them provide the email list. They’re telling me I should harvest emails from people who visit the site. Well DUH if people were visiting my site why would I need an email campaign to generate traffic? Does anyone have any experience with legitimate email advertising where can I get a list of contacts?

I have a large email list in MS Excel, I wish to import it to Outlook, How do i do this?

I am into Stock Market and I want a technical analysis software to be programmed and made for marketing. The software will implement some of my ideas. Do I contact big software companies or should I meet free-lance software developers? What will be more cost effective?
