Your own website hard coded is the best way yo can market your business and do business with clients safely. Blog platforms used as websites are not safe and can be costly to keep safe. However if you are not experienced in coding the blog platforms might be for you just remember you will need protection especially when you attach social media as a widget to your website. Social media should never be your website. Branding your business is most important and having a social media brand associated with your business will not get you the goal you are striving for. 

Have your own web hosting and domain. This is what how you can market your business. Attach your social media links buttons, widget, box to your website for streaming purposes ... whatever you post in social media you can post through email marketing which is another avenue you can use for free when you have your own web hosting.

Too many businesses promote Facebook, Twitter, and IG simply because they don't have their own web hosting. The best results began with you ... market you ... your business, use social media to get the work out but direct them to your website.
