Best outdoor speaker option?

Did they tell you where they would put the speakers? Depending on where you want them, getting an inexpensive stereo receiver a pair of outdoor speakers (Polk Atriums, for example) would be less than half that and you could probably do the installation yourself.

Would you be interested in doing it yourself?

If so, you can get what you need a lot cheaper and save on the labor. If not, I would think for the speakers and amp and remote and labor that might not be a bad deal if you like what they are offering.

You might want to ask *how* they are going to run the wires and detail exactly where they would put the speakers. That would give you an idea on if you might tackle it alone.

Do you have any paint that matches the house or trim? Running wires along the outside is easily made to look "hidden" by painting over them to match the siding/trim if you follow trim edges and siding lines.

They would probably just drill a hole through the wall and silicone the annular space from the inside and out - you can do that (check for studs first). Plan ahead for entry/exit points and routing wires.

If you NEED a remote outside, that may be difficult to do too easily and the Bose may be a better deal if they have a remote that isn't IR.
