Air Whit? Really? I didn't think they took anyone with less than 500 water landings?
If you are going to contact Seair, be aware they normally only put a van on floats once or twice a year. If you're doing a wheel van endo, try and get a bit of ICUS up to LEI.
That Garrett van looks ok, wouldn't want to be too much outbase stuff with it though, especially without ground power...
