People should choose more healthy appetizers by determining how much calories it contains, how much transfat and how much sugar/salt that is in the item. These are important factors in determining a healthy appetizer.

If they are very good friend of you, you should not charge. Otherwise charge according to how much you work.
they should charge just enough but not too much
The amount of fruit and cheese you would prepare for appetizers would greatly depend on the number of guests you will be serving.
you should charge 3.00 dollars or 1.00 dollars

Without knowing specifics on the salad or appetizers or the time frames involved, I would hazard a guess and say both should be kept refrigerated until served. If the appetizers are to be served hot, they should be heated just prior to serving. If the appetizers have been prepped days before consumption, then freezing might be considered. Most salads that I'm familiar with would not take to being frozen and don't have much of a storage shelf life.
The rate you should charge depends on how long it takes to get all of the trees planted. You can multiply how much you expect to make per hour by how long it takes to get an estimate of how much you should charge for the job.
