I need a grammatically complete sentence.

The entire project is projected to cost $500,000 cdn, we were able to raise $300,000 cdn.

While most English speakers would understand this, it is a run-on sentence comprised of two phrases. One of these may be easier to understand for your readers:

> The entire project is projected to cost $500,000 cdn. We were able to raise $300,000 cdn.

Or

> The entire project is projected to cost $500,000 cdn; we were able to raise $300,000 cdn.

Using a semi-colon is ideal because it allows you to add two short, but related, thoughts into one sentence.
