I have done it myself using my Sony DVD/VCR combo which has dubbing
ability. It will generally copy a vhs to a dvd but not the other way around.
If you don't have access to one then I really think you would be best off
to simply buy the DVD if it is available. I think it would cost you more
to have somebody dub it for you and I don't know who provides that
service.
Sorry couldn't be of more help.
