Three things, in order: a reply, a call, then a proposal. You'll hear back within one business day, and it will be a considered response from someone who has read your message, not an automated acknowledgement. From there the process stays deliberately short, because nobody contacts an agency in order to sit in a pipeline.
If you'd rather read before you write, the home page has the short version of what we do, our web development and SEO services pages explain what we build and how we price it, and the full portfolio at devarko.com/work/ shows the platforms we've shipped for clients in Pakistan, Kuwait and the USA. None of it is required homework; it's there if it helps.
