Need Toy design sketch

Hi! I'm working on an original character concept for small collectible figures (blind-box style) and love your style — wondering if you'd be interested in a paid project. Quick summary: an original, non-human, non-animal creature (not a robot or tech design either) — cute and rounded like a collectible toy, but with real attitude — inspired by Jamie Hewlett/Gorillaz-style linework and expression, simplified into a cute chibi form. First concept is a matched pair (one girl-coded, one boy-coded), punk attitude, slouched posture, big rounded innocent "puppy dog" eyes, spiky hair, and literal puffy under-eye bags as a signature feature (not makeup) — kind of a "tired troublemaker with a soft side" vibe. Looking for 2-3 rough concept sketches first to see if we're aligned, before commissioning full refined designs. Full IP would transfer to me on completion (work-for-hire). What's your rate for initial concept sketches, and do you have a link to more of your portfolio?
