Here's the rule that describes what you must do:
Va. R. Sup. Ct. 1:12 - Service of Papers after the Initial Process
All pleadings, motions and other papers served after the initial process in an action and not required to be served otherwise and requests for subpoenas duces tecum shall be served by delivering, dispatching by commercial delivery service for same-day or next-day delivery, transmitting by facsimile, transmitting by electronic mail when Rule 1:17 so provides or when consented to in writing signed by the person to be served, or by mailing, a copy to each counsel of record on or before the day of filing.
Subject to the provisions of Rule 1:17, service pursuant to this Rule shall be effective upon such delivery, dispatch, transmission or mailing. Service by electronic mail under this Rule is not effective ifthe party making service learns that the attempted service did not reach the person to be served.
At the foot of such pleadings and requests shall be appended either acceptance of service or a certificate of counsel that copies were served as this Rule requires, showing the date of delivery and method of service, dispatching, transmitting, or mailing. When service is made by electronic mail, a certificate of counsel that the document was served by electronic mail shall be served by mail or transmitted by facsimile to each counsel of record on or before the day of service.

I would just use the one I provided if you are able to draft it on your computer and print it out. I would save time. I wasn't able to find a fill-in Virginia court form. Maybe you'll have better luck.
