I need to overhaul a CRM with features similar to Another CRM

Hello there,

We currently have a CRM in place with quite a number of features in place including invoices, support etc. But those are only some of what we are looking for. We need a redesign of our current CRM at IGS to fully integrate all features and looks to that of the Shore light CRM.

IGS CRM: (Built on CodeIgniter) - Modules have been disabled to make it look clean but has stuff on the settings menu.

Admin user login - admin@igsedu.org
pass - admin@igsedu.org

Shorelight CRM:
website - https://admissions.shorelight.com
login: ceo@indoglobalstudies.org
pass: Indoglobal@6

We need almost as much as exact replica of the shorelight CRM. Please have a look around in both and see
1. How well this is feasible?
2. The cost of the same? If it's feasible in this budget?
3. The time taken to finish it? ETA?

Looking forward for your replies.
