Since you appear to need many parts, I expect it is time for you to learn to make them for your self. For one or two parts it is better to let someone that already knows how to make them when you need large numbers you need to learn to make them yourself. These two tutorials apply to current Fritzing versions.

I lately learned there aren’t links to the videos in Old_Grey’s tutorial so you need to do a google search for the title and then they come up on YouTube.
