Right place at the right time.
You do know how to run the $ on a big job right? Get your contracts looked over by a lawyer etc. They say it is easy to loose on the big jobs. I have made the mistake of thinking that the big jobs make more money. But they don't. My most profitable job is still in the 10G range.
I still have a milliion+ dollar house that owes me 2G's.
My connections with the builder will help but if the Landscape architect feeds the design to his contractors what am I to do. I have been trying to market us to designers and LA in the last year. It has paid off. I am working with a pro photographer to get some quality images on our web site. We are also going to have a nice printed brochure/portfolio aimed at the professional designers and LA's. Yellow pages ad just isn't going to cut it.
