Not successful in creating my first screen

[zepper]

Hi guys,
I am starting my online t-shirt printing shop http://www.zepper.in. I have been working from home. Previously i used to print and sell mobile phone cases. But Now i am planning to start my t-shirt printing business. As a matter of fact, Its not easy to print and supply tshirts at home. if you do not have sufficient knowledge in this field. I have tried to built by first DTG but i was unsuccessful and ran out of money due to high cost of parts and other things.If i buy a commercial DTG it would cost me more than $10,000 Which i do not have.
So i opted for screen printing. Bought all my materials for screen printing. Setup a small screen printing machine. But the problem is i cannot produce perfect screen. Maybe its light problem or the applied substance to the screen is thick. I am not able to open the mesh properly. Guidance is needed. Thanks.
