A large number of probes have been landed on Venus already throughout the 70’s. They were able to take pictures and measure temperature on the surface for about an hour at most. That was over 50 years ago. I’m sure we are capable of constructing machines that can withstand the conditions for much longer now. In 30 years though we might not even deem that necessary and just capture an asteroid and orbit it around the planet and build the base of operations atop that.
