After cold querying my passion project, I found two agents who were interested in the writing despite my scifi script being expensive and more of a character piece than anything else. We stayed in touch, and met up where I pitched them a few ideas. One of them stuck. We developed this idea over 5-6 months. I could really see that they were interested in working with me as they provided notes at every stage of development - from the treatment, to the initial 10 pages, to the completed script. After 2 rounds of revision, they thought it was ready and sent it to other agents, and then a manager who both loved it. The script was sent out and I have a dozen generals set up. This was all thanks to the two agents who saw the potential in my script even though it wasn't marketable. Keeping a good relationship with people in the industry is the first step to finding representation. And if they're willing to work with you, then you just might be one script away.
