Yet the most part of the signal jammers market is filled with the most popular combinations of jammed frequencies, and it is not easy to find a jammer with rare combination of the jammed frequencies.
In order to deal with your small situation you can use desktop cell phone jammer and desktop UHF VHF jammer together. This strong combination will allow you to block all necessary frequencies at once. But if you wish to use one jamming device, then look at this multi-frequency desktop jammer that blocks all mobile phones plus part of UHF band, yet VHF is not included there.
So the choice is completely yours and in any case I hope that your small situation would be successfully solved thatnks to your decision and the usage of the jammers ;)
