Winter Housea Cross Stitch Pattern by Artecy Cross Stitch

I am looking at the pattern for Winter House and it calls for 94 colors of floss. I did not see a drop down list to purchase the floss, does this mean I need to get the pattern first and then order the floss? Also, I am looking to buy Aida 14 count material with the grids already placed on the material, do you offer such a product? Thank you!
