Networking with Multiple Agencies/Sources

Hello, I am a single prospective adoptive parent. I initially thought that I would commit to an agency until a friend who recently adopted forwarded an e-mail from another agency that was looking for home study approved families for an "urgent need" situation. This made me start questioning whether I should tie myself down to one agency or keep my options open. I contacted an independent home study organization and I start my home study next week (with no agency commitment yet). Can anyone give suggestions on how I can network with multiple agencies or sources once my homestudy is complete? Is this even possible? Thanks!
