Finalising some fashion pattern drafts

Hi all, i am a fashion designer. looking for a pattern maker who can go through some drafts of mine to finalise (correct seam allowance, proving seams/joins etc) And possibly grade the size group if you know how to. Styles are relatively simple. Mainly trousers and simple block dresses. Budget will depend on the number of styles you'd like to take. So 1 style for $50-$80. 2-3 styles would be maybe $150-250
