building a website for small home business where to start

hey my aunt has a small home business(does about 100k in sales a year) and she is looking to start a website. i offered my help but dont really know where to start. basically looking to allow customers to purchase her products online. i figured initially customers could do just email the orders and then pay for the purchases via paypal. any recommendations on webhosts that would accommodate this and not cost alot? i have essentially no experience building a site and hopefully didnt bite off more than i could chew.
