What being based in Las Vegas actually changes is narrower than it appears, and it is worth being precise about. Local knowledge matters for local search, for understanding a specific market, and for referral introductions. If your customers are in Reno or Phoenix or Atlanta, I do not have the local relationships there, and I will say so rather than implying otherwise. What transfers completely is everything structural: positioning, pricing, site architecture, measurement, and the sequence in which things should be built.
The parts of the work that benefit from being local are also the parts you can supply. You know your market, your competitors, and the peculiarities of your area better than any consultant would after a month of research. The arrangement that works is that you bring the local knowledge and I bring the pattern recognition from watching the same problems recur across many first year businesses.
Practically, remote engagements run the same as local ones. Scheduled calls rather than drop ins, written recommendations you can reread rather than advice given verbally in a meeting, and shared access to the accounts being worked on. Several clients have found that written recommendations are more useful than a conversation, because a document can be returned to in six months when the decision comes up again.
If you are local and want to meet, that is genuinely available and often pleasant. It is not necessary, and it does not change the quality of the work. Time zones within the continental United States have never been a real constraint. Beyond that, it depends on how much overlap the working day has.
Time zones matter more than distance in practice, and it is worth being explicit about working hours at the start rather than discovering the mismatch during a project. Within the continental United States this rarely creates difficulty. Beyond it, the question is how much overlap exists in a normal working day, because a relationship depending on two hours of shared time each afternoon works differently from one where a message sent in the morning is answered before lunch.
For clients outside the valley, the local knowledge gap runs in both directions and is worth using deliberately. You know your market, your competitors, and the local conditions that shape what works. What transfers from here is the pattern recognition from watching the same problems recur across many first year businesses, and the arrangement functions best when each side supplies what it actually has rather than one party pretending to expertise it lacks.
