a few people tell me that I have to use a State Licenses Plumber to do the job. I also have had a few people tell me to do the job myself upto the final connect and then call someone in to finish the connection. Is this legal. If not, how else can I go about getting my plumbing hooked up w/o breaking the bank. I know I have been told that a permit costing around about $460 has to be purchased. Do I go ahead a purchase it and do the work, or should I do the work and then call someone to do final connect and let them purchase the permit. I know no plumber wants to tell me a cheaper way to have this done, but I have a "limited" budget and what others are trying to charge me ...I can't afford. Any suggestions are great. Thanks!

My husband and I have bored through the walls for the drain and water lines and have also hung the sink which is now ready to be worked on, just afraid to move forward and do the work myself if it is just going to cost me more in the long run. I have about 12-15 feet of pipes to have installed as well as the venting.....
