'Temporary Residency Visa', is a bit of a mix up. 'Temporary Residency' is also Provisional Residency (just a play on words), and that is something you would have until you qualify for Permanent Residency or citizenship. Costs run as long as a length of string, but it seems you get what you pay for as far as lawyers assistance goes, cheapest start at about 500US more expensive run at around 2000US, timescale now from medical to cedula seems to be between 4 and 6 months, all being well.
'Temporary Visa' is something you will get in your passport while you wait for you application to be processed, if you apply for residency then it is free, included in the costs of your application.
I think you want a 'Visitor Visa', and I think they run for 3 months at a time, tops and I have no idea of the costs, someone else will shout out I'm sure.
If you are not entering with a need to work or drive then I'd not bother, the exit taxes are still in place and are the cheaper option.
Taxes? .......................................
There are other visas but this seems to cover what you are asking.
