I draw pencil sketches and that's what you need. I think I will be a prefect fit for this task. From the rough sketch you provide, I will be able to draw a perfect sketch for your business. I have HTML and CSS knowledge as well so if in future anything needs to be migrated to web, I can help you there as well.
In my pencil sketches, I pay attention to finer details. I would like to know the deadlines for this work so that I will be able to figure out if I can give my 100%. If you give me a chance, I will not disappoint you and that's a promise.
