Need a specialist to create an online store on a turnkey basis

You need a specialist to create an online store on a turnkey basis. We have an online store it needs to be remade (make another on another engine): art-hobby.com.ua / engine is very disliked, design is not very functional. From you I would like: Offers of your version of the store vision, cost (design layout - the finished store is on the way out). What style do you see in our store? Let me remind you that our main production products are stencils, (this is the second one on the website), should be reflected in the design. There is also a retail store. We do all kinds of workshops, hand-made. Here is a link to our website: art-hobby.com.ua/. Girl artists, I think that's the main thing.
