Sewer Support, please!!!!!!!!

Aaron and I are gearing up for the basement remodel. We also got the final bill from the painter for the exterior work, and it was almost $17k!!!!!!!!!!!!! We know that this restorative work isn't cheap but... whew! That's a lot of money. Forgive us if you see tons of shots of our freshly painted exterior for the next couple of weeks.
So, we're looking for some ways to save money. We were planning to pay a plumber to relocate a sewer pipe from the middle of the laundry room floor to the corner of the laundry room where it will be used as the drain for a sink. Now, we are wondering if we can do this work ourselves. Aaron feels pretty comfortable renting a small jackhammer to break up the concrete around the pipe, and in the area for where it needs to go, but he doesn't feel so confident with the plumbing- how to connect to the old sewer pipe, how to angle the pipe so the water flows down into the sewer, etc. etc. Is this a job for a professional, or can we tackle it? If so, how? Google hasn't been very helpful, but maybe housebloggers can come to the rescue once again. PLEASE don't be shy- comment or email with any tips. You'll have our eternal gratitude, and if you live nearby we can trade a work day, even.
Thanks!
