Hello, my name is Elena, and I want to ask you something about the online store that you want to be done.
It is great that you want your site to be on Wordpress, because wordpress offers the best SEO and you will be in higher places in google and other search engines only for a few weeks.
About the design of the site, I can show you many ways to set your site to be very easy to work with and also with a great design. I have many ideas about it, and if you want to, you can write me a private message, and I will show you what I think is the best design for that kind of sites.
About the time to be done, I think that If you show me what you like, I can make it in one or two days, but If you dont have any ideas about the design, I think it is the best to show you a few things and you will tell me what suits to your taste!
I will show you a few videos that shows in details how you can add, edit, view and delete a product in wordpress if you are interested and want to know how you will work, it is very easy!
If you need any advice, feel free to write to me! I will be glad to help.
Best regards!
