Hello Trish,
I have to agree with Cathryn. There is a dedicated group here at the VAF for subcontractors. The person in charge of the group is Collete. She would be able to find you sub-contractors to most anything you need done.
Here is a
link to the group.
Here is more information on
Collete.
Please reach out to her. She is very helpful and has found sub-contractors for me in the past.
