If you are spending money on renting, it could be cheaper to hire an electrician. Think of going to pick up the ladder, moving furniture, setting up the ladder, changing lamps, moving ladder / furniture to get eyeball recessed light, blah blah blah. I know this is a DIY site but sometimes you can hire a professional and get it done for not much more than getting everything and doing it yourself. If that eyeball is hard to get, or what looks like another fixture on the left, then these really could make it worth it.
You can also buy your own lamps and have the electricians just do the labor only, but if the electrician supplies the lamps then they might warranty them and if a product failure happens, then you don't have to mess with it again.
Whatever you do, use a LED lamp and a manufacture that you are familiar with. Newer technology LED's cost more than older technology and the biggest difference between the two is the lumen output. Normally DIY's will have brand names and they will be older technology lamps. Use a color of 2700 to 3000 kelvins that will be about the same as incandescent colors (warmer). Good Luck!
