Assemble trampoline

Hi there, I have a 14ft trampoline from spacejump that needs to be put together. I have had this since Christmas but my son broke his arm hence why it's not up . It also has a basketball hoop and ladder etc... I am a single mother so lowest price possible would be much appreciated. I also have a still set pool that needs to be put up , I would like this put on concrete so I don't have to take it down so if you could please recommend underlay or what ever else I need I will sort out payment.. it has a filter and pool cover .. unsure of budget so just put 25 sorry first time on here ..thank you
