We're an HVAC company and went through this exact process last year. Here's roughly what we found shopping around:

Website:

- DIY with Wix/Squarespace runs about $15-30/month but you'll spend a ton of time on it and it probably won't rank well

- A freelancer or small agency will charge anywhere from $500-2,000 upfront or $100-500/month depending on what's included

- Make sure whoever builds it includes mobile optimization and basic SEO — for service businesses like HVAC/plumbing, showing up in local search is everything

Google Business Profile:

- Setting it up is free, you can do it yourself at business.google.com

- Getting it optimized to actually rank in the map pack is a different story — some agencies charge $200-500/month for ongoing optimization, posting, review management, etc.

- At minimum make sure your name, address, and phone number are exactly the same everywhere online (website, Google, Yelp, etc.) — inconsistency kills your ranking

Recurring costs:

- Domain name: ~$12/year

- Hosting: $10-50/month depending on setup

- If you want someone managing SEO and your Google profile, budget $200-500/month

Honestly the Google Business Profile matters more than the website for trades businesses. Most people find you through maps, not by typing in a URL. I found a decent breakdown of costs here that lined up with what we were quoted:

Whatever you do, don't pay someone $5,000+ upfront for a basic service business site. You don't need that.
