If your opening up a thread for your service then you should provide some of your samples in your thread itself for the potential buyers to check. Don't expect people to contact you for the samples because a lot of people are there to provide these services.

Also, you can list your gigs on fiverr site because there this segment got a lot of demand. I too sell some of the intro videos on fiverr and receive few orders every month.

Be weary, folks. This user is paying you to falsely pump the book's ranks, which can be viewed as highly untrustworthy by certain forum DT1 and DT2 members. If you're not willing to get a default red trust on your accounts, I'd suggest not posting in this thread that you're actively willing to participant in this untrustworthy offer.

Just a fair warning.
