The first way I know how to get the word out is to get the idea legitimized. Get other famous architects to promote your idea. Simply enter and win some design awards competitions. There are more awards programs out there than there are Lady GAGA songs on the radio.
Pick what awards programs best matches your project. If it is unbuilt then win a PA Award. If it is green-win a COTE award- or green award from Contract magazine. Artistic interior- just win a BOY award and be published in Interior Design Magazine. Have a small project- enter the AIA small projects awards. Residential, enter the AIA housing awards and Residential Architect awards. Are you emerging? Better win an Architectural review emerging architect award. And did I mention AIA awards at local, state, regional and national levels. Record interiors and record houses are fab. Asid, green awards, id magazine awards, better homes and gardens has awards.
Believe me if you do remarkable work, there is quite a few awards programs to enter.
Do awards lead to work? Indirectly yes. But directly lead to work? It can happen. I was fortunate enough to win an AIA National Honor Award just a few years after hanging out my shingle and a small mailing I did announcing the award lead to the Broadmoor Development Company Project and the Quality Telemarketing project.
Awards have been very, very good to me.
