Your business is accounting, not being a webmaster.
I recommend that you use Site Build It (SBI) for your website work. This will allow you to concentrate on your accounting business and let SBI do most of the work.
Do not think that all you do is push a button and your SBI site is on autopilot. The initial set up will require some hard work, but from my experience, the SBI process will lead you through finding your niche market for your accounting service, naming your website, and building your site.
SBI will then promote your site to the search engines. The search engines will send your customers to your website. Once the search engines have delivered the customer to you, it is up to you to close the deal.
I recommend that you build a service sales website to promote your accounting service.
Good Luck and may you always have a backlog of customers
