Here are a couple good lead management tools. (this is not an ad, just advice;)http://getdashboard.com/
This tool is super easy to use and cheap. This is want you can use it for...
let's say you have a web site or lead source for good real time leads, and you want to use some of the leads for your self and sell some for a profit to a client. If you have an account, which is under $15, and your client has an account, you can deliver leads to them with out showing your source. Fairly simple and effective.http://leadmesh.com/
This is a serious lead management tool. You can run a huge business with this app. It has a ping tree, APIs for very slick lead delivery and a co-reg ad server. I run one path with this tool, it's great. It does cost $250-$300 per month. I my opinion it's totally worth it, 7 years I built an app that cost me six figures and it does basically the same stuff. Crazy how things change.
I hope it's ok to talk about resources and tools I use to make money. I'm not making money promoting these tools, I just figured it could help people in the forum. If this is not good, just let me know. I'll stop.
