Two quick thoughts....use the same blue in a more saturated version ...very pretty color, btw. Or surrender to the bathroom and find a color that is a pale version of the yellow-y beige, if you haven't tried that path already. It will have to lean toward a pale golden color....not a beige. Beiges have all kind of undertones you don't want to mess with. I struggled with a bathroom that had gray and peach tiles and finally succeeded by painting the walls gray. I kept looking for a good coordinate and finally just had to work with what I was given.

There is a good sized difference between full and partial overlay style doors in cost most of the time. Also, there's often a decent charge to upgrade to painted cabinets. Between those two things a mark up of 30% isn't completely out of line. But it's also possible that he's charging more because he doesn't like building them... and that's a pretty reasonable thing. I too like to make more money if I'm doing something I don't like. And I think he's right. Painted Shaker style doors are a little trendy right now. I love em! But they are a little trendy.

I like a green-blue suggestion above, but your exterior colors are so neutral that you can choose almost any color you like and it will be another step to make this house "yours". A bright blue door will make a bold statement and will be an eye-catching focal point distracting from poor landscaping. On the porch, you can add an outdoor chair and decorate it with some bright pillows that will match your front door. If there is not enough space for chair you can add an unusually patterned rug. Read more about how to choose a color for the front door and how to paint it properly. On both sides of the stairs, you can add pots of flowers it is a good idea to make your entry more inviting and interesting. Some inspirational pictures:

Garage door same color as siding so it recedes from view as much as possible. Front door a bright white like your window trim - or a creamy white like your house trim (fascia) will make your front door pop (like it should). Or, you could paint your front door a lime green or other bold (orange or yellow) not-dark color like below. As mentioned you have mainly glass so the green/color border is really diminished. Landscaping would really help your home. Right now all the emphasis is on your driveway and garage door. Post in the landscaping sub-forum for a landscape plan and plant help.
