Custom websites, e-commerce and AI automation for Erwin businesses — published pricing, one senior team, delivered remotely from Denver.
Erwin is South Dakota's 282nd-largest city — a close-knit community of 40 people where a business's website is usually its first impression. Aenfinite designs, builds and maintains that first impression: custom websites, e-commerce stores, and AI automation that answers your leads in minutes, delivered to Erwin businesses by one senior team.
Everything we deliver is digital — design reviews, staging links, launches and support all happen online, which is how one senior team serves Erwin, the rest of South Dakota, and clients in all 50 states without franchise-style handoffs. You work directly with the people building your project, and every engagement starts from our published Denver pricing.
Technical foundations plus content that actually ranks.
Conversion-focused design built around your customers — not a template.
Fast, secure custom builds on modern stacks.
Editable, SEO-ready WordPress builds you own outright.
Stores that are fast, trustworthy, and easy to run.
Workflows and agents that answer every lead in minutes.
A phone line that never misses a call — from $1,500.
Follow-up, reminders and pipelines that run themselves.
Custom small-business websites run $3,000–$15,000, e-commerce $8,000–$40,000, and AI automation starts at $1,500 — always quoted fixed after a free consultation. See what a website really costs in 2026 for the full breakdown.
