amazon web servces for my sitemaps

Hello. I have a web hosting service that claims they have unlimited disk space usage for accounts, but when i created my sitemaps, they demanded that I delete them because they were taking up so much space. I explained to them this was not for storage purposes but actually being used as part of my website, but then they didn't care and suspended my account anyway. My question now is, could I use "amazon web servces" to store my sitemaps remotely due to lack of resources on my main website hosting account? If so I would like to hire someone experienced to transfer the sitemap files for me and set all the technical things up for me. My budget is only $30
