Website for art gallery with shop

dear all, I am looking for someone to help me build a simple website using one of the website builders (Tilda, wix or your choice ).
We opened a new art gallery and would like to showcase the artworks online.
There are several categories of artworks: painting, limited editions, sculpture, and jewellery.
it will be great to have a drop-down menu, and in each category to have a submenu with the names of artists. There are 7 painters, 1 graphic (limited editions) and 2 sculptors. each of them has a selected number of works. So as I see it there is a main page that has a logo and about and a pop up receive our news form, a selection gallery with 2 drop downs - one with a category and in every category - names of the artists, and then you select the artist and each one has a page with artwork. The artwork will have different photos and has to be clicked to be able to purchase.
Or your idea on how to make the gallery website.

I would also like to have the online shop installed (again using either of the website builder of your choice with a simple clean template)
I do not know what is the cost of the template based website. Happy to view offers and show the artwork if needed. I have all artists information and descriptions of each painting or sculpture and the price in the 2 catalogues that I can send you.
I am happy to talk about price.

Thank you
