If you're tight on budget you could look on Gumtree (or similar for your area) and find free wooden cabinets/bookcases that are deep enough and you lay on their back to make it into a 'box shape', and take out any and all shelving. If you're not in a hurry to put glass or plexi in the front (when someone could help you out), that could be a good solution.
