Looking for some much needed assistance!

Does anyone here run a solo shop and do the Google PPC lead generation that they have process down to the T that they don’t mind sharing? I’ve been doing it since last year and can’t figure out to get net positive ROI on my spend. Any help will be gladly appreciated. I under time is of the essence so I don’t mind paying for your time either. I really just need guidance as to better close the leads and how to follow up with them from beginning to end.

Is your issue lead volume (thus CPL), lead conversion (leads to sale) or both?

What’s your current CPL? (And what is your website/market?)
