Fixing and improving Coldfusion-based site

My site was built in Coldfusion 10 years ago with a members-only area. Over time we have messed up quite a few pages and forms through incorrect copying or accidental deletions. We now need two pieces of work:
1 Essential repairs
2 Site improvements
Initially I would like to engage a Coldfusion expert for 1 or 2 days (8-16 hours) to carry out Part 1 - the essential repairs. If things look promising, the project will then expand into Part 2.
The actual amount of time allocated to Part 1 will be determined following discussions with the successful bidder, but it certainly won't be less than 8 hours.
