Some of those exist, usually billed as implementation partners that also can do whatever dev work you need. The problem is getting marketing leadership to believe they need those services. Usually you have a handful of technical marketers shouting from the rooftops asking for dev support. The CMO goes and talks to the dev team and they are reassured that there is no need to outsource, there is a perfectly good team in house that will get around to it eventually. I've had the best luck bringing in a firm as part of an implementation and then keeping them on for a few months to help with odd jobs in the guise of support. Executive leadership in sales and marketing is typically clueless as to what their teams need too be successful. It isn't in their job description, it isn't what they were hired for.
