There are a ton of great resources in these threads, and like Ryan said, it's busy season and this sub-forum usually seems a little slower in the summer months because of that. Guys usually chime in, don't get discouraged and negative so quickly and you'll have better luck hearing back from other guys.
As for marketing, I don't do, nor have I ever really, done a ton of paid versions. Good work spreads and word of mouth is huge. Also an awesome website with great SEO is absolutely paramount. Usually guys have links to their sites in their signatures on here (if they have a business). Check those out for ideas. Google Adwords is also a good idea, as well as Facebook and Instagram. Having a fully set up yelp page for customers to leave you reviews for others to read can be beneficial. Following up with past customers and impressing current customers any way you can are things that should naturally be done, but always a good reminder to hear them again. Hopefully that helps some.
