I'm familiar with Excel, and I'm confident to be able to do the task required. I need you to supply the trade association's website url, so I can see the list of their members. It is hard to estimate the time required to do the job, without knowing how many members involved. I also need your email, so we can communicate better.
Below is my plan:
1. I will check the trade association's website and see the list of members
2. I will create the excel spreadsheet with a sample format, and some member details.
3. I email the spreadsheet above to you for approval, to make sure it is according to what you expect.
4. I will finish the remaining task, and email it to you.
