"to find" or "finding" after the verb "help"

I want to say this sentence:

Could you help me to find a financial support please?

Would it be more correct to say to find or to say finding? Is there a general rule to determine whether to verb or verb+ing is more correct? Is there a better way to construct that sentence?

Answer

You can say:

1. Could you help me to find financial support, please?


2. Could you help me find financial support, please?


3. Could you help me in finding financial support, please?

The second sentence is normally used in informal contexts, or when speaking. The OALD has the following note about using "help somebody to":

In verb patterns with a to infinitive, the ‘to’ is often left out, especially in informal or spoken English.
