Best way to build a Lead Generation Site/Page?

Been out of the game for a few years… And now I’m starting over and I have a friend that wants me to build a lead gen site to generate leads for his business.

Not just email address but contact info and phone numbers etc…

What is the best, fastest and cheapest solution

PS: Not a newbie Started selling online in 1998 but have not done anything other POD for a couple of years. So what the best route these days? Build my own or use a platform and which one?
Thank you

I would use wordpress and beaverbuilder simple to use any any wordpress plugin will work with your site if needed in the future

WordPress + Elementor

Clickfunnels for life man.

I need some courses. Can you suggest me some courses and sources to buy ? Thank you

You can outsource the site or use wp.
