Mr Sinha, I’ve been in that soup too. Been conned a lot of times before actually getting my website miraclepreneuring.com to it’s current state.
Funny thing is, the guy who did the job was my friend whom I’ve hired as the CTO of my company. One thing I’ve learned is that in the tech space, you must have sufficient knowledge about the whole process if not first hand knowledge.
Have a friend or follow tech blogs closely to know the exact face value of everything. It’s a very dangerous game with these tech people, they play around a lot.
I got lucky though, and wish the best for you too!
