If you can, do it yourself. Drop the pan and inspect for any metal shavings or unusual amounts of clutch material. This will also give you the opportunity to change the filter, which would be a good idea as you're a bit over-due. If you take it in, take it to a shop that will drop the pan and change the filter.
If all else fails, and you know of a good instant oil change shop (there are some good ones, but you have to do some searching) then having it done that way is better than just leaving it.
