Will be visiting the workshops near DHA area today to find some mechanics and denter painters. @sH3ikH told me about a denter but it would be difficult for me to follow up with that guy because of my official commitments. Wish me luck guys! 
Also need your opinion about the denting painting work involved in the picture. Here's my take on the project (which might be wrong due to my non-experience):
1- I feel that it shouldn't be really difficult to form the tank into this shape since it's not a complicated shape.
2- I plan to get the chassis sand blasted first and then painted.
3- Handle bar seems to be a little more difficult
looking forward to your feedback
