Hi newbie here, will probably do minor reno to new place soon. For those of you who purchase your items (I'm concerned about electricals mostly - lights, fans) separately either from taobao (online etc), different pieces from different shops, do you engage the shops to install items or do you look for a separate electrician? For those whom you engage from shops, do they mind installing things not bought from them (of course not for free)? Or do you just DIY everything? Thank you for your time! (I'm a DIY-er, but I also understand my limits on installing stuff... LOL)
