If you want really fast results at a price point of your choosing then the only way to go is through paid ads. You can copy an ecomm template, put in $50 in FB or Google ads and see how many leads you generate. If results are satisfactory, then it’s up to you to know more about that. At least you’ll know what direction to go in.

You can do SEO, cold calling, word of mouth, but it will take waaaay longer to see results.
