Try iFixit.com. They have on-line manuals for taking apart many Mac models. I know they have ones for iMacs and Minis, perhaps they have one for a MBP. The manuals they do have are all photo illustrated. There are other companies that sell bit and parts of Macs, for DIY repairs. If you don't want to do a DIY repair, an Apple store will charge you the most - though if you have Apple Care people here have reported that on occasion an Apple Store will ignore the warranty voiding coffee bath and do a free repair.... but I don't know that you can count on it.
Good Luck. I dumped coffee into my MBP earlier this year. After 5 days of drying I was luckily enough to avoid any damage. Though I suspect I've voided my Apple Care if there are any moisture sensors inside. Oh well.
