OT: VPS with Routed IP space

Anybody know of or have recommendations for providers of small VPS-line boxen (or alternative solutions) to serve as GRE endpoints? (for a small amount of IP addresses, /29 or /28 at most) I am finding a lot of places that will give you extra IPs on the box itself (oftentimes out of the provider's own larger unsubnetted prefix) but I am looking more for a setup with a single IP on the box and a prefix routed to it. TIA for your insight. Alex (if you or your company can do this, direct solicitations are okay too. do keep in mind it's just a personal project and I do not have larger commercial volume at this time)
