Hi,
I Would like to work for you on this project to add required features.
Thank you for sharing detailed information that helped to understand the high level requirements.
I have gone through to all details and would need to discuss the review the existing application.
Its clear to remove limitations and allow you to upload the csv data, but would first need to review what limitations are there and after removing them it should not affect the application and data quality.
You need to have an invoice module as per your excel template, please do share the template.
You need to have an easy way out to insert new bookings or home allotments.
I can use jquery data table, which will help you to search, sort existing records and allow you to insert new records online.
Would perform ajax operations to insert data so it will not refresh page but just the table or grid that shows data.
I am expertise in php, asp.net, MVC, codeigniter, mysql, mssql, plsql and other related technologies with 7 plus years of experience in IT.
I am a full stake developer and can work independently to deliver quality work within timelines.
Thanks,
Sudesh Arora
