WordPress Isn’t Just a Toy—When Done “Right” It Can Be World-Class
WordPress is the world’s most popular CMS (40%+ market share). The advantage is high flexibility, but the disadvantage is “fragility” without professional care. Our Premium WordPress Solution service focuses on making websites “Clean, Fast, and Secure” according to Enterprise standards to support long-term business growth.

Specialist development our own dev team handles (no middleman)
These four are built in-house, because they need someone who reads code and knows WordPress at depth.
- Custom WordPress plugin development — from 999 THB: a function no off-the-shelf plugin covers, written as your own plugin that works with any theme and any page builder. We scope the requirement with you first, then quote on the real work.
- Hand-coded site to WordPress 100% — from 2,500 THB: move a site written in code (HTML/CSS/JS, Bootstrap, Tailwind, Astro, Next.js, Nuxt, Hugo, Jekyll, Eleventy, hand-written PHP) onto a WordPress block theme your team can edit on every page — no build step, no Node on the server.
- Headless WordPress + static front end — from 5,000 THB: WordPress for editing, static files for visitors. Saving rebuilds the site in about 30 seconds, with draft preview before publishing. Requires hosting with Node.js, SSH and cron.
- Catalogue migration + technical SEO — priced per project: move 1,000+ SKUs off a closed platform with URL mapping, per-URL 301 redirects, canonicals, sitemaps, Search Console checks before and after, and post-launch monitoring.
Every service is priced based on actual scope — assessment is free with no upfront cost. Request a quote or chat on LINE.
We migrate websites from every platform
Whether your site is on a Thai site builder, an international platform or an old CMS nobody maintains any more, we move the pages, products, photos and categories, and set 301s for every old link, so the Google rankings you have built up don’t disappear with the old system.
Don’t see your system? Just ask. Some platforms let you export from the admin; for those that don’t, we collect everything from the live pages. If your platform has announced it is closing, start early.
Real example: moving a 1,576-product Porsche parts store from iGetWeb to WordPress · Service details: catalogue migration + technical SEO
Affordable Starting Prices, No Shortcuts
Our starting prices are within reach of small businesses, but we don’t cut corners on standards, because cheap, rushed websites often come with risks:
- Using Nulled Theme/Plugin (pirated) containing Malware
- Abandoning projects when systems have complex problems
- Low security, customer data may leak (Compliance Risk)
At Southern Whale we emphasize Quality & Long-term Partnership. Our service fee buys “peace of mind” and “standards.” Our team uses 100% genuine Licenses with verifiable work processes.
What We “Don’t Do”
We respectfully decline some work types to maintain highest quality standards for our clients.
- Low-budget websites requiring pirated Theme/Plugin: Because security is non-negotiable
- Rush jobs 3-5 days: Enterprise-level work requires design, development, and detailed system testing
- Websites just to “have something”: Because we believe websites are the most important online storefront for business
Deliverables
When the project ends, you get more than just a website.
- 100% Ownership: You own Source Code and all data
- Genuine License List: List of genuine theme and plugin Licenses verifiable
- Documentation: User manual and maintenance documentation
- Security Baseline: Enterprise-standard security settings
- Long-term Roadmap: Recommendations for future expansion and development
Elevate Your WordPress to Another Standard
Don’t wait for your website to break before fixing—prevention is better than cure.
