Why responsive matters specifically in Sylhet
One site that works for the phone in Sylhet and the laptop in London
Sylhet is the one market in Bangladesh where your website gets judged twice. A local customer finds you on Google while sitting in a CNG near Bandar Bazar. They open your site on a Symphony or Redmi over a shaky 4G signal. The same week, a probashi son in the UK opens it on a 15-inch laptop. He is deciding whether his family should trust you with money sent home. That is why responsive website design in Sylhet is harder than it looks.
If the page is a shrunken desktop layout on the phone, the local buyer leaves. If it looks cheap and broken on the laptop, the overseas son quietly tells the family to look elsewhere. A responsive site in Sylhet has to pass both tests at once, and most do not.
I'm RH Fardin, and I've spent about 5 years designing and coding websites for Bangladeshi businesses. Some are Sylhet owners who already paid once for a site that "works on mobile." What they got was a desktop template with the columns stacked. That is not responsive design. It is a checkbox.
Real responsive work decides what a 360px screen shows and hides. It decides what loads first on a slow connection. It also plans how the layout breathes when it opens at full width on a desktop. I build from the small screen up, not the other way around.
I work alone on purpose, and for Sylhet that matters more than you'd think. The person you message on WhatsApp is the same person who sketches the wireframes and writes the HTML and CSS. I test it on a real phone and a real laptop, and I push it live. There is no junior who has never seen your shop on Zindabazar, and no account manager forwarding screenshots.
Your probashi family member in the UK may call at an odd hour with a question about the site. When that happens, there is one operator who actually knows how it was built.
Pricing is posted up front, so nobody has to guess. Responsive sites start at 50,000 BDT for a focused 4 to 6 page build. 90,000 BDT gets a 10 to 12 page business site with deeper content. 1,50,000 BDT covers larger marketing sites with custom sections and integrations.
Fully custom builds with dashboards, multilingual setups or unusual layouts start at 3,00,000 BDT. You pay 50% to start and 50% on launch, by bKash, Nagad or bank transfer. Payment sent from abroad works fine too.
