What type of budget do you have to work with? Because your budget is going to impact what type of suggestions people will give.
This is a good budget google:
Eachine EV800D 5.8GHz 40CH Diversity FPV Goggles with DVR - which you should be able to find on many store fronts.
If your limited to Line of site (or other close range situation), that should cover you for a good while, if not 'forever'.
For a camera/VTX system, there are quite a few options to deal with.
if your being price conscious and and are running type time of limits it sounds like your using, finding something like one of these would be a good solution:
-
Caddx Ant AIO FPV Camera
Personally, I would get something with a Circularly polarized antenna (see attached photo, I couldn't find this model quickly on the internet)
