Reliable Wifi internet and TV packages

We are in process of buying an apartment in La Dorada.  We intend to spend winters there and a few weeks over the summer too.  My husband works from home, all of his work is via the internet and so we need it to be very reliable. 

Last winter we spent in La Cala, Costa Del Sol in the apartment they had Olivenet and it was very reliable. I have contacted Olivenet and at the moment they do not cover the La Dorada area.

I wondered if anyone lives in La Dorada area and can recommend a suitable provider who they know can install these services for us?

Any advice is appreciated.
