Pricing - offer starts at (lowest price possible) OR have an 'Inquire' button, use the service called tawk.to to do live sales chats. I was once working at a software startup, all of the cheap pricing, we almost never had people ask questions, but for the higher plans, nobody purchased without chatting to us on live chat first. The web app i mentioned is free.

What it's missing - testimonials OR working for a big brand. Need to install 'trust' into your brand. I'm a bootstrapped startup, so I don't think startups are your best target market.

What I'd suggest: running tests with pricing & the live chat service. Likewise, I'd do the same with the web copy (USP). Chart it all and analyze it.

Another way to market your service, find out something your customers really need & build that as a free service. Then, grow your brand & sales from their.

Paid advertising, I wouldn't worry about it. Just focus on trying to get engagement from social media & growing your followers.

Craigslist, you can promote your service there. You could set up a bot that automatically posts to Craigslist for you OR a bot to automatically email out prospective clients daily.
