Try a company called newitts sports online. I purchased 2 full size pop up goals for my u12s team. They are easy to set up in under a minute and the come in all sizes at goods prices. 

I personally like the Kickster Goals. Same size as a mini soccer goal. When I used mine, once you get the hang of it, I could put two kickster goals up in the same time as two coaches used to put up one mini soccer goal.

Pugg style pop up goals are good as target goals (other makes are available) and Bazooka target / training goals are good although they tend to be a bit more expensive but they are more substantial than the pop ups

Hope this is useful
