Hi guys!
Ive read your project and, even though I would need more info, i would suggest a priori, to go with digital marketing. This means:
1. First, run a little analysis on your website, branding, etc.
2. Look at your competition, potential customers and possible partners.
3. Check your pricing. See if its not too low or too high.
4. Then, we start with sales. I would probably run a campaing on Adwords but social media is also useful, first one is more expensive, second one takes more time.
5. Of course, we need to some email marketing to take advantage of your past customers or those your made an inquiry and never bought your service.
6. As part of the pricing policy, we can think of running a promotion. This would depend on many factors including your cost.
anyway, this is only a brief summary. Lets talk, know each other and see how can I help you.
Cheers!
Lucas
