Hello,
I think that you should add tags for all of your relevant skill sets, and list them in your profile, however you can create separate listings for services on Clarity. In your case, it might be advantageous to create separate listings for each category that you specialise in, all from the same profile.
In my opinion, the purpose of your profile is to build trust, expertise and professionalism within the fields you work in. The profile should state what you know and your experience without trying to convert a sale; the listings are where sales are converted.

Since i ones scraped a list of all topics here, feel free to go over the list and find the ones that suits your services.

Hello! I think Clarity is best for the consulting portion of your business.

I have not seen much demand for folks looking for the service-side, most often, they are seeking advice.

Position yourself as an expert partner, share your expertise, and I'm confident the trust built on those calls will result in service work.

All the best,
-Shaun

There are a number of categories that you can select for your profile, but it sounds like you could use the "Topics" option to list the different problems you're able to help with.

In general, I think having multiple topics in one profile is better than trying to maintain separate profiles.
