Or you could just install them, adjust string height and intonation if necessary, which is exceedingly simple to do with tons of how-to's available on this very website, and play.
I haven't been playing for 44 years, but I've never had to pay someone to install strings for me.

I just switched strings on my Jazz 5 from D'Addario steel rounds to Roto 77s. I am now setting up my bass as the tension is way more and the action is quite high. The string tension is a blessing to me I don't want my B or E flapping around if I hit them open. I like the 77s, plenty bright enough for me even though I just switched from the super bright Prosteels.
Do it,
fnord!
