18 months to get to 70 visitors a day is a tad slow if you've been working on the site daily. You could stand on the corner outside and hand out pamphlets to people and expect better results I'd guess. You mentioned having to wait so if you aren't doing anything to improve results you might just be waiting indefinitely because it doesn't sound like a sandbox to me though I'm sure it feels like one.

It doesn't matter how high you can rev the engine so to speak, it matters that you get traction and keep it over time. Check the site for glaring SEO issues to fix, get rid of all content that isn't unique or is of poor quality, and connect with people who are interested in your niche online or off. Slow and steady wins the race.
