You just need to create an online shop where your product is your service, that's still appropriate. And you can advertise your service through
that shop where people or potential customers will just view your shop and look for your portfolio's , sample creation's programs and other services
that you can offer to them. You don't have to do talking just able to have customers.
You have to make it compact. If you can't do the design have someone do it for you in a simple one or you can even select it from the ready made webpages and all you have to do is encode the information needed to complete the page to make it run.
