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 and opens your site on a Symphony or Redmi over a wobbly 4G signal. The same week, a probashi son in the UK opens your site on a fast connection on a 15-inch laptop to decide whether his family should trust you with money sent home. If the page is a shrunken desktop layout on the phone, the local buyer bounces.
If it looks cheap and broken on the laptop, the overseas one quietly tells the family to look elsewhere. A responsive website design in Sylhet has to pass both tests at once, and most don't.
I'm RH Fardin, and I've spent about 5 years designing and coding websites for Bangladeshi businesses, including owners in Sylhet who already paid once for a site that 'works on mobile' and got a desktop template with the columns stacked. That is not responsive design, that is a checkbox. Real responsive work decides what a 360px screen shows and hides, what loads first on a slow connection, and 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 sketching the wireframes, writing the HTML and CSS, testing it on a real phone and a real laptop, and pushing it live. No junior who has never seen your shop on Zindabazar, no account manager forwarding screenshots. When your probashi family member in the UK calls at an odd hour to ask a question about the site, there is one operator who actually knows how it was built.
Pricing is posted up front so nobody has to play the guessing game. Responsive sites start at 50,000 BDT for a focused 4-6 page build, 90,000 BDT for a 10-12 page business site with deeper content, and 1,50,000 BDT for larger marketing sites with custom sections and integrations. Fully custom builds with dashboards, multilingual setups or unusual layouts start at 3,00,000 BDT. 50% to start, 50% on launch, payable by bKash, Nagad or bank transfer, and remittance from abroad works fine too.
