San Luis web design FAQ
Will someone from Aria visit my business in San Luis?
No. Aria is based in Curitiba, Brazil, and works with every client online: material, change requests and questions go by email, and you review the website on a temporary link before it goes live.
Is a website worth it for a business in a town of 597 people?
Yes, because the competition is county-wide: Costilla County counts 351 nonemployer businesses and 50 with employees (2023). Being findable outside San Luis is the point of the website.
Can I show customers in Blanca that I cover their area?
Yes. The website can carry a service area section naming Blanca, Sanford, Manassa and any other town you cover; you send the list by email.
Is there a setup fee?
No. No setup fee: you only pay the $89 monthly fee, after you approve your website. There is no lock-in contract either: you can end the service whenever you need.
