I grew up in Fairbanks, Alaska (20+ years), and while I wish I were still there for the hunting, I am not personally interested in hunting moose. The other species available there interest me more.
That being said, I have a friend from the lower '48 that wants to shoot an Alaskan moose with trad gear, and we are planning a future DIY hunt there. (I would almost prefer to save money on moose tags and just tag along for the ride, perhaps as the dedicated videographer. I'd rather save the money on out-of-state moose tags and just shoot small game along the way.)
I have family that are still residents of AK, some very active and successful hunters. One of these family members in particular is one of the most successful hunters I know, and has taken several moose over the past few years. He has also helped several AK-resident friends of his to locate moose and take them with firearms. He will be a big part of our DIY hunt in a year or two, and says that it will be tough to go DIY and get into a high-percentage situation without flying in somewhere. This is from a guy that owns multiple snowmachines and four-wheelers, and a riverboat, with several years experience as a river-rafting guide in the interior. There is a lot of hunting pressure in areas that the average Joe has access to.
Unless you can get help from someone who knows how to hunt Alaska, and who knows of accessible areas where the hunting pressure is light, I would recommend paying a guide. If you are just looking for an Alaska-hunting experience, and would be content looking for moose (but probably not taking one), shooting small game along the way, DIY would work... because that is likely what would result.
