Who you are actually hiring
Most "WordPress experts" in BD are just plugin installers. I am not.
There is a difference between someone who can install a downloaded theme and call it a day, and someone who understands what WordPress is doing under the hood. I sit in the second group. I know what a bloated theme does to your load time, why your shared host slows to a crawl at peak hours, and how a stack of conflicting plugins quietly turns your admin panel into a minefield. When clients come to me after a cheaper build went wrong, that is almost always the story: too many plugins, a nulled theme, no updates, and a site nobody dares to touch.
I work as a solo developer on purpose. Agencies in Dhaka sell you a senior in the meeting and then quietly hand the work to whoever is free. I do the opposite. The person you talk to is the person writing the functions.php, configuring the caching, and testing the checkout on a real phone before launch. That means fewer people to coordinate, faster decisions, and a single point of accountability when something needs fixing.
Around five years of doing this has taught me what WordPress is genuinely good at and where it is the wrong tool. It is excellent for content-heavy business sites, WooCommerce stores, blogs, and anything where the owner wants to edit pages themselves without calling a developer every week. I will tell you honestly if your idea actually needs a custom web app instead, rather than forcing it into WordPress and charging you for the privilege.
Pricing is plain. WordPress builds start at 50,000 BDT, with structured tiers at 50,000, 90,000 and 1,50,000 BDT depending on page count, custom design and store complexity. Fully custom work begins at 3,00,000 BDT. Payment is 50% to start and 50% on launch, and you approve the design before you pay for it. No surprise invoices, no "scope changed" excuses halfway through.
