 I'm sorry, but I think that there's a good chance that your dog: 1) will be next to impossible to housebreak when you're gone that much, 2) will most likely bark all day (probably will start around 4 - 5 months), and 3) will likely be pretty neurotic because you won't have time to socialize him properly to other people and other dogs.
 
 If you could afford to send him to doggy daycare, I'd feel better about it.  I don't think someone coming in to let him out once a day is enough contact with others.
 
 I'm sorry.  You asked for opinions so I've given you mine.

  I'm not sure on this one, I work 9-5 as well and  I had a very well behaved dog (yorkie-poo)  used a baby gate in the kitchen and left my him with my cat (tabby 4yr old) food,water, toys, and he was NEVER a barker or Neurotic! I have a neighbor thats a stay at home mom and she never heard a peep out of my dog during the day, House breaking was not that difficult .. I have friend with small dog that stay at home all day and there dogs potty training went no faster than my dog being that i work ? Doggy daycare is expensive I would look for a play group or better yet invest in puppy kindergarden which will be nice cause it puppy and you time not to mention that your dog will meet other Local dogs and you will meet other local people (get a weekend doggie play group started) 
My situation may or may not be the same but i have 3 children a neighbors with puppy & older small dogs for socialization, I think if you dont make a big deal about leaving and dont make it high tension situation when leaving it makes all difference. you have to be very commited to making your situation work for you. I would plan ahead on a schedule that maximizes your time with your puppy. and that fit your current life style.. once a schedule or plan is started stick to it  
 
  
i hope it all works out good luck !! and  
CONGRATS !!!!!
