I know you all are constantly asked for placement advise but us newbies are so unsure of ourselves!

I have and 8 yo dd who is well above level in reading but does not enjoy writing one bit. Copy work and dictation will probably cause issue at first. But she does want to learn cursive and has enjoyed using tracing paper to copy my cursive words. She will be in 3rd next year and turns 9 over Christmas.
I also have a 6 yo dd who is still learning to read. She knows all the sounds and can sound words out but is impatient when it comes to actually reading. I plan on starting her with SCM's Delightful Reading soon. Her handwriting is better than big sisters, but I haven't attempted to have her do much besides what is in her handwriting workbook. She will be in 1st next year and also turns 7 over Christmas.
I also have a very bright 3 yo dd who will turn 4 in the fall. I'm considering LHTH for her.
And bringing up the rear is my 1 yo ds who will turn 2 in the fall.

My thought is Beyond for my older 2. I just think I will be overwhelmed to try and do them separately in bigger and beyond and finances are an issue in that choice as well.
Any advice or wisdom would be greatly appreciated!
