Shared hosting or VPS?
 

The site which i'm gonna develop has no visitors initially and gradually it gonna get some goodwill in the future and get visitors peace by peace.
I have very small budget now to put on this site. So my thought is like shared hosting is good option right now because not having visitors right now, but when site reached stage of more than 5k visitors, then i need to plan for VPS.

Here comes main issue, i have huge file setup and database. My wordpress theme and plugins together size itself 70MB and database which gonna use once started running also take lots of space like users upload there doc files.

So which should i go for now - SHARED OR VPS?

I would recommend you to contact Hostwinds.com team and tell them your specific requirements - they will find the best hosting solution for you.
These guys do anything to keep the sites up. Their support is outstanding when you compare them to all the other major hosts.

Transferred all my sites to kvchosting.net and no regrets! Uptime: perfect, Service: perfect.
I like their cheap cloud ssd hosting solutions:

The exceptional support that I have received has helped me learn an immense amount about web design and hosting.

Go for VPS hosting which provides dedicated server resources.VPS hosting is better option to host sites of reasonable traffic.

VPS Hosting is similar to owning a Condo. ... On a Virtual Private Server, you are allotted resources that are not shared by everyone. The overall CPU time and memory are shared across all accounts on the machine, but at the same time, portions of those resources are always dedicated to each account.

If you need offshore vps hosting, I would highly recommend superbithost and their services.
No hidden fees or surprises, very reliable service: https://www.superbithost.com
I have not really had to use the customer service, because everything was fine with them (no downtime and no problems).

I believe Hostwinds.com is the right place to get hosting solutions at.

- Network and server uptime have been perfect (my site is always up and accessible from all over the world),
