Have a pro soda blast (or shells or whatever media is preferrred locally) the bottom and then use your staff to fair the underbody and shape the foils. With that many people and time, you should be able to get the job done. As with most big jobs, the prep work is 90% of the work.
Attempting to do this job by hand may well cost you your crew, unles they are all teenagers who dont know better...
