Per the documentation you have several ways of specifying the 
parameters NonlinearRegress is to find

as a list of symbols --- default starting point will be 1.0 for 
each symbol

as a list of {symbol, number} pairs --- starting point for 
symbol is number

as a list of {symbol, min, max} triplets --- requires symbol to 
be between min and max

as a list of {symbol, start, min, max} list --- starting point 
is start, requires symbol to be between min and max
