I'll have to agree with swamp rider on this one. it's really not hard to do a lift yourself and only requires some basic tools and locktite. Give yourself about 6 hours to sit and read through everything, double check and take photos as you go. They do come in handy if you need to look back and see how something was put together.
Does the 270 include the lift or is that just all labor? If it's all labor then i would do it myself.
You learn things by doing it yourself, you know what and where everything is and when your done, you can sit back and admire your accomplishment.
