Unknown. There are plenty of affordable 3rd party solutions depending on dimensions and budget. Most involve some sort of die-cut foam to be removed bit by bit until it fits sufficiently. These solutions are quite popular. Pelican and SKB are two companies I know of that offer such options, but they are not the only ones.
Alternately, if it fits, a laptop bag can work quite nicely and serve as a suitable case. Readily available in various sizes, these can range from super affordable to very expensive. Expensive ones tend to be the high-end leather ones. The nylon ones work just fine. Ensure they have good padding and you'll be fine. Shoulder straps, pockets and more make it convenient to carry accessories, cables and DI's around. You should be able to get good protection in your budget, just ensure the case will fit your VMS4 first.
Another option is to have a hardshell case made, either via a company like SKB or Gator(who can make custom cases). These custom molded cases tend to be expensive since it might be a one-off. Might want to shop from their commercial, military and industrial series to find a cost effective case.
A hard case might be the other way to go by one of the many companies that make road-worthy cases, such as Anvil, Jenner, Calzone and others. The only problem wiht these options, outside of weight, is the number of options, ranging from corners, rails, handles, hinges and more. The costs tend to be rather high but most people find the costs justified by the end product.
While the plastic cases tend to usually offer rubber gasket seals, the ATA-type cases often do not. Unless you're leaving them in standing water or a downpour though, this is typically not a problem since the lid lips tend to nest a bit which is going to keep out almost all the moisture and should not be an issue.
You being in France shouldn't limit your choices too much as I'm fairly sure you shop all over Europe to get your stuff anyways. I would advise stay with domestic routes just to keep your costs from skyrocketting due to inflated shipping charges, but you already knew that.
Have fun.
