Need to move the dryer vent up by 3ft
It'd be better if you modify the duct.  A dryer vent that fills up with lint is a serious fire hazard and even if you're sure you'll clean it regularly, the next homeowner may not.
You can find a lot of videos on Youtube about how to work with that kind of ducting.
I'm not sure if you'll need any materials; it may be possible to re-configure what you already have.  But if you do need anything, the HVAC section of your local home improvement store should be your first stop.
