Friends don't let friends terminate twisted pair cable into 8P8C plugs. Without lots of practice it is likely to go wrong and end up with a poor connection which somewhere down the line will be intermittent. Decent crimping tools are also quite expensive.
Get a testing tool as well, and leave enough slack at each end in case you need to have another go or two—you can always stuff extra length somewhere, but you can’t make cut cables longer.

Punch down cables in your walls/floors to sockets which is much easier to do and buy factory terminated patch leads. If you can't screw the box to the wall you can use a surface mount socket as a flying socket, something like https://cpc.farnell.com/pro-signal/psg08000/socket-surface-rj45-cat6-single/dp/CS16167
