Maximise my opportunity

II have just started my recruitment business, working from home. While I am not great with social media, I would like to maximize my opportunity with the social media platforms I currently have. My recruitment focuses on Technical and Engineering staff, and I use my website, LinkedIn, and Facebook to do so. Unfortunately, I do not have very good technical knowledge with these products, so I am looking for someone to help me make them better and to direct traffic to those sites. I have a small budget as finances are tight.
