I have got some interesting research topic and I would like to seek financial support.

I will talk to my faculty while the topic may not to be covered by my PHD founding, what should I do?

I have heard that there are a couple of research agencies or web sites who help researcher to contact industry or institutes?

Any recommendations from you will be appreciated? (sprout)

As far as I know there is a so-called Research Council in most countries that gives grants. You should fill in an application form where you state your topic and precise information concerning your work and if they like the area you are working on, there is a chance to get a grant. As for me, I am going to do a part of my thesis abroad - in Norway, where I will collect some necessary data.
