That is a question that we must answer together. I know a great deal about my own business, and very possibly nothing about yours. I am in the business of presenting information so that it is compelling and easily navigable. As an artist and designer, I know how to get people's attention. I also know how to present information in a simple to complex, drill down for detail kind of way.
I assume that you know your business better than anyone, otherwise you wouldn't be doing it. I can help you sift through complexities of your work and help you make that information comprehensible to your audience.
As a starting point, most contemporary websites are ‘responsive’. That means that they reformat for optimized viewing on the device on which they are being viewed.
If your website changes frequently, then you may want some basic CMS, or Content Management System. That will enable you to make changes to the content of your website yourself, without the need to engage frequent design services.
If you are in a competitive field, then you may want comprehensive SEO, or Search Engine Optimization, so that your website ends up on the first page of a search query.
These and many other issues go into the creation of an effective web presence. I can help you decide what is best for you.
