A lot of the GoDaddy plans are for light hosting and basic websites. GoDaddy does offer advanced hosting plans and it sounds like you need something more robust than a basic hosting offering? If you were a client of mine I might even look at putting you on your own server? Hope you find the hosting you are looking for.
...turns out that my two cents is worth less or more depending on the current exchange rate.
