The most important thing for a vocalist is to be heard.
Check the backpages of the music press for recording studios in your area. Or better still ask people for some recommendations.
Invest in your career by spending a couple of hours recording some stuff professionally, whether it be accapella or to existing instrumentals.
Seek out talent shows, singer's nights, music biz workshops and seminars. These places are where the people you want to meet go to meet people like you.
There's no quick fix answer to your question but this business is all about belief, hard work and an unrelenting approach.
