Sounds like Bnos Chana / Halichos might be perfect for you. It is a more relaxed Bais Yaakov school with two programs. The Bnos Chana program is all day limudei kodesh with a strong emphasis on mussar lehaskil. There are tests and minimal homework, but it is very relaxed. It is a small place with a lot of inidividual attention.
Halichos is a more intense program geared towards girls who want to learn a profession on a high level without giving up on a full seminary experience. So there is a half day limudei kodesh, tiyulim, shabbatonim etc. The professional study options are: Graphic Art and Design including Photography; Early Childhood Education, and Cosmetology.
It is a great place and the girls who have gone are very happy (it is going into it’s fifth year).
Good luck
