1. I do need the support to implement the legalization part (I don't know how to run c-corp or something)

2. For free? What is the profit for them?

4. Suddenly not, I rely on 3rd party providers and they cost me some money.

The problem is that I can't edit post right now. So here is the link: https://goandcall.me (I've got very bad communication and copywriting skills but I promise I will improve them).

The main idea that you can get a link or widget for your website, email signature or get it per prospect via API. This link will help your customers call you without any plugin or additional software. Free for customers, paid for you. You can manage links and numbers (activate, deactivate, assign schedule).

1. You are definitely overestimating how hard this is. Look up contract CFO firms, and you should be able to get part-time support for logistics like that (as well as helping you get your books set up and do taxes).

2. Many are non-profits or have a mission that is unrelated to them making a profit. They often are funded by VC firms, companies who would like to provide services to companies in the accelerator once they have money (law firms, etc), and companies that want to raise their own credibility in the startup scene (3dsystems, or area-focused companies like GE maybe funding accelerators that work in batteries). Some also get government grants.
