Development on an existing website

Dear,
I’m selling family portrait made of bricks of Lego, pls find my website : https://les-portraits-de-felie.com/
I would like my customers to be able to choose online the bricks they want to do the characters, with a preview so they can arrange it online.
I have around 400 bricks available online but no preview possible on my website right now
My request for the tool :
– Get a preview of the characters made of Lego bricks for the customers
– I would like to be able to update the tool by myself to manage new bricks and delete some
– I add a small description for each brick, i would like to get it in French and English. With the translation apps i use, all is translated, except the name of the bricks (i use Product option by Bold app).
I would like to get a quotation for this development.

Thanks,

Florence
