There's a job posting board where you can post such an announcement.
Are you really talking salary or just need a consultant to take on this project and fix it for an agreed upon fee or hourly rate?
I think consultant will be a good idea to fix it for an agreed upon fee..Thanks. any idea how much will it be?
There's no way anybody could answer that from what's been posted so far. You'll need to set up a detailed description of the problem with sample files if you have any so that the prospective consultant can determine the scope of the project. Then it's a matter of negotiation.
