Best sites/services for quality personal prints?

I've been working on some vector series over the last few months, and I think now that I'm sitting on about a dozen of them, they would make nice prints at a larger size (in the 24x24" arena as they are square).

If I wanted to get my own little shop running out of my portfolio site, what would be the most reliable and cost-effective method of getting prints made on demand for anyone who were interested?

I've never really ventured into marketing my own stuff as "fine art," since this is coming from a design portfolio. Any tips appreciated!

Quick example of one of the pieces to give an idea of the palette/kinds of edges that could inform the material its printed on

Thanks all!

Great design resource
