Traditional Agencies

The expensive standard
  • 6 to 8 weeks development time
  • Focus on pretty design, not revenue
  • Unclear pricing with hidden charges
  • No sales understanding
  • Outdated technologies
Result: High costs, little revenue

Client Voices

What our clients say about working with us.

Anonymized experiences from real projects. Names withheld for confidentiality.

2 months ago

Our old site barely brought in any inquiries for almost three years. We had practically written it off. After the redesign with Giorgos, four really good B2B inquiries came in the first week. That was a real turning point. What I particularly appreciate: everything was transparent, no fluff, just got it done.

I previously had really bad experiences with two other agencies. With Giorgos it was clear from the start what we get and what it costs. No extra charges, no surprises. Delivered on time. Our reservation system has been running without a single outage since the switch.

Owner, Bar & Restaurant Verified
6 weeks ago

We were really looking for someone who doesn't just click together a website but understands our client structure and our topics. That worked. The response time was impressive — usually within hours, not days. We recommend him internally.

I founded SGA because I was tired of seeing companies pour money into pretty websites that don't sell. My job isn't design. My job is your revenue.
— Giorgos Sannis, Founder

Why I founded SGA

I started building websites for friends and family. Restaurants, small services firms, lawyers. What I kept seeing: most agencies deliver a pretty shell with no substance. Templates for €5,000. Designers who have never sold anything.

I chose a different path. I study your business first, understand what you sell, to whom, and where the bottleneck is. Then I build a system that solves exactly that bottleneck.

Today I work with companies across Germany, Austria and Switzerland. Every project goes through my hands personally. Whoever works with me, works with me — not with a team I've never met.

Answers

Your questions. Clearly answered.

Direct answers without marketing speak. If anything is missing, write us.

What does a website at SGA really cost?

Our prices start at €999 for a Starter website (3 pages, mobile-optimized). The Growth plan costs €1,499 and is the right choice for most businesses. Custom solutions from €2,199. The price in the quote is the final price. No extra charges, no hidden costs.

How long does the project take?

A Starter website is delivered within 5 business days after briefing completion. Growth and Custom projects are also finished within a week. I always deliver on time. That's a hard guarantee, not a marketing claim.

What happens if I'm not satisfied?

Every project includes two free revision rounds. We work together until the result fits. If you don't want to continue after the first draft — no problem, you pay nothing. I only work with clients who are truly on board.

Do I get hosting, domain and maintenance included?

Yes, hosting on premium servers (Hostinger Business or VPS) is included for the first year. I can register a domain for you or you can use an existing one. Maintenance costs €19-49/month from the second year, depending on scope.

How is GDPR compliance handled?

Every website comes with a GDPR-compliant cookie banner, privacy policy, imprint template and secure EU servers. Analytics is anonymized and cookie-free. You're legally compliant from day one.

Can you redesign my existing website?

Yes, but usually it's not worth it. Fixing an existing website often costs as much as building a new one and brings worse results. I'll give you an honest recommendation in the first call. Rebuild or optimize.

Who's liable if something goes wrong?

SGA is a registered agency with full professional liability insurance. All contracts are under German law. You have full ownership rights to your website, including source code.
