I have a number of things that I use for small percussion instruments (shakers, rattles, bells, triangles, etc.) ... depending on the gig and how much I need to bring. For recording sessions, I have two, large wardrobe cases with drawers. They are 5-feet tall, and almost 3-feet wide. Not practical for gigs obviously.
I have a rectangluar road case that I use as a table, if I'm standing to play. It can carry small percussion, but there are no compartments, so I have smaller cases inside the road case to keep things separated and protected.
I have two of these cases, except mine are longer than these ...
SKB Equipment Case 
When I use these I have small bags and cases to hold and separate everything, then put the small cases in the larger cases. I can stack the two SKB cases to use as a table if I'm sitting down to play.
I have the LP Percussion Table that I use ... so I don't always need my cases to act as a table. I also have two tray tables that clamp onto any kind of stand (ie. cymbal stand, mic stand). I use carpet samples to pad the surfaces ... which fit my trays or the top of my cases.
I also have a number of hard plastic cases that I purchased at Wal-Mart years ago. They have a flip-lid, in two sections, and a way for me to padlock them if need be. They are stackable, so I can stack them as needed to create a table height for sitting or standing.
I just need to post some pictures ... then you can get some ideas and find something that works for you.
I like to be organized, so each type of instrument is grouped together. For example, all of my triangles are in a zippered bag. Doing this allows me to consolodate everything, keeping like instruments together, while protecting them individually. The triangles don't need protection, but everything needs to be protected from them! So by separating it allows me to grab what I need and place it in the larger case. Then I use pieces of foam to place as needed to keep things from moving around. The movement is what tears up your instruments. If you have a good case, and the toys are packed snuggly, you don't need a lot of padding inside the case.
I was looking at a case on eBay a few months ago; they are around $60. Use the Drummer Cafe eBay Search and look for
Pro Audio 6 Drawer Portable ATA Work Case w/Wheels. These have little drawers and you can flip the lid to make a table out of it. This might be perfect for you in a small gig situation. Read the comments from buyers! Some thought this thing was too flemsy, which was a turn-off me ... and the fact that the drawers we shallow ... around 4-inches high. That's just not big enough for my needs. I would rather have 4 drawers that were 6 or 7 inches high.
