website help/adivce!!!!!!?

[D123]

Hi I am about to make my e-commerce site I was just wondering would this work for example when i gain more experience in html and php would it be possible to revamp my site or to delete the woo commerce page and then upload my own create website through the ftp on hostgator.

can you delete the whole of the woo commerce page and then upload a website you created through ftp will my domain still be their?

Also do you recommend big cartel over woo commerce please give your reasons why as well. Another thing lets say i was to move from woo commerce to shopify, big cartel or magneto would it work and what would i have to do? I hope i am not stuck to woo commerce once am with it?

I heard that generally the plugins sometimes crash when things are updated with woocommerce.
