Small PHP Fix Required for Wordpress Plugin

Hi, I have a custom appointments booking wordpress plugin that we have located two small bugs in. #1 - In a sign up form, one text input box will allow the viewer to enter lots of text, however in the backend database where it saves the info submitted info it only saves the first 255 characters it seems. We need it to save everything they input and change the max to say 1500 characters. #2 - There is also another field called notes that is accessible from the backend where the admin can make any notes about the booking. It will allow info to be entered into this text box, however the info entered is not saved when you update and save the changes. I think these are small items, but I need someone who can fix fast and get it done properly the first time. Thanks.
