I (and many others) could rebuild it, but to put it in perspective, a full rebuild kit from bob roberts is about $49 shipped. Chad at arcadecup.com is about $55 shipped but doesn't have the hot or regulator, it produces an awesome picture though with no curl.
Shipping each way will cost a total of about $23-$30.
So you are $70-$80 in without paying a guy for his time yet. Gotta figure 2 hours if a guy goes through and reflows all the solder and does a clean job. Minimum $10/hour and in reality it should be $20.
Adds up real quick
I think a couple of guys have had rebuilt g07 chassis in the for sale section for $100 or less recently.
