Move fast--I am thinking a lot of hydroseeders went belly-up in the last two years due to slow building and the poor ecomomy. There should be used equipment on the market at bargain prices--even if it is bigger than you really need. The need for burn out repair will be much higher this year than ever before.
And learn to do sod cheaper--if you are competing on price and the customer wants to cut corners. If he wants to skip soil prep and fert...so be it...charge for each item separately so you can remove the extras and compete with whomever you must compete with.
