Hi Ahsan,
Sure! I can help you with these type of projects.
If you want to set up voice based support(where you give support through phone for your customers) you need a very good location where there is easy accessibility to telecom.
The next thing is web based support
wherein you can provide support to your customers through email and chat mode.
Both of these need different type of investment. For voice based support you need to invest more on hardware(phone lines,instruments.etc) but if you are going for web support you need to invest more on softwares. Better if you go in for a CRM package to maintain customer details.
I suggest you to get hold of clients who wants to outsource their business or approach some software companies for whom you as a team can provide technical/non technical support.
let me know if you need anything else
