I created a brand new gig for making websites and blogs mobile-friendly: https://www.fiverr.com/kim_talented/make-your-website-responsive-and-mobile-friendly
It has gotten so popular that I’ve been able to “pause” my other web development gig. Usually I get 4 persons contact me all in the same day and 2 of those I can work on at once and complete in 3 days or so. The third and fourth persons I can take but their delivery time would be 6 days out if I make the order right away. However, when I tell them it takes 6 days, they don’t want to proceed because that’s too far away and go with someone else. I don’t want to lose customers. What should I do?
