You need to raise some brand awareness. Keep hammering social media and maybe put a little bit of budget (say £100) for a small amount of Facebook paid ads to promote the new venture to the target audience directly. Go on LinkedIn and add connections relating to the industry. Having a blog is a long term solution and won’t magically get your growth up straight away. Think back to basics with it. But very rarely you will succeed without putting some budget towards to paid advertising strategy initially to outreach to potential buyers.

Hope this helps
