this is so easy to do yourself - just rent the tools from a hardwareshop (for example CT hardware in tmn mega rents out professional tools if not mistaken). installation should be only a couple of hours even if you never installed one before since its only the base cabinets.

i have used the IKEA install-team before: they are really good. highly recommended to save the work. BUT: i used an outside once to dismantle and re-assemble a wardrobe. headache lah - cannot do it properly even though i provide manual to them. have to supervise and still can screw it up. so in the end i had to take it down another time and re-assemble myself. lucky for me the wardrobe was good enough quality to tahan another disassembly and reassembly.

last time i almost needed a fret saw and some other tools. they got cement mixer and other pro tools. can even rent out a karcher from them (80 bucks per day if not mistaken). quite convenient.

anyway the hole for the kitchen sink is really easy to do - the sink comes with the required dimensions. use a drill to make an opening along the line or inside and then cut the peace out with a fret saw. make sure you stay inside the given line - its easy to cut if you place the board between two kitchen cabinets. vacuum the dust away while cutting. once you cut out the opening seal it kitchen-type silicone to prevent moisture seeping into the particle board. install kitchen sink after you fit in the particle board (easier to handle) and then install the outlets and cut the hole for the faucet if needed. i have done it twice before - two people can do the job just fine. only thing to be dilligent about is taking proper measures and maybe triple checking them just in case. dont want to waste a board right?
