hi there,
i've read your description, i think that is more like manga assitant than editor. but anyway, i think i may be quite a fit for your needs, here are my samples of manga style illustrations

feel free to check the rest of my samples here

i am willing to do the test (i'm assuming you want me to ink a sample of your sketch?) for a low fee since it's for sample (the cost would depend on the complexcity of your sketch of course)
best regards,
jul
