Sumproduct - complex sum arrays

See the attached sheet. I am struggling with how to do this. I need the SUMPRODUCT to calculate accordingly. Maybe a mix of SUMPRODUCT, OFFSET, and ISBLANK would solve this, but I am not smart enough to figure it out.

The SUMPRODUCT needs to only sum the italicized rows by Resource Group (Column E), but filter by Community and Type in Columns B and C. Problem is that these data sets are not inline with the italicized lines (they are usually above a couple rows depending on how many resources are on the project).

Also, note that conditional formatting is using ISBLANK to make the bold and italics.

Any idea how I can pull this off. Let me know if I need to explain this better.
