I think it is high time you two got yourselves some books and education and learned to work on the bikes yourself. If your one and only shop is like this, buy your stuff from them but do the work yourself. You can always have them do the difficult stuff like install the headset or true wheels, but the rest you should be able to do and save yourself a lot of frustration. Yeah, it means some grease so don't wear one of your cute outfits at the same time.
