Hi Conial,
I have reviewed your attached PDF and have completely understood the modifications you want to conduct in existing PO Management System. I can definitely assist you in this project as I do have experience of 7+ years in CodeIgniter Framework and have already completed couple of similar jobs.
If possible, I request you to schedule a meeting with me so that we can finalize the scope of this project and clear any further misunderstanding from both the ends before starting your work.
I look forward to your valuable response.
Thanks and Regards,
Manish N.
