Honestly, just having a site for your resume doesn't seem like something that's very high-traffic/high-space intensive (unless you have vids as part of your portfolio?). In that case, getting a new domain name is probably around $8-$10/year, depending on your registrar, which shouldn't break your bank. Then, if your webhosting company offers the feature, get an Add-on domain (basically, all traffic from newdomain.com points to files in a subdomain/subdirectory of your main site, but the visitor doesn't get any info on the main site as far as I know). That seems like the cheapest solution to me. If one of your hosting packages isn't nearing the max and take a bit of extra traffic/space, that's probably the best method?
