Hi
How many PDF you have got and when you expecting this to done by. I have more resources as well so if required can work in parallel to get the work done ASAP. I am based in UK , so feel free to get in touch via phone or email.
I will get one sample done for you today , so you can verify the quality as well, anything you not happy you can stop the work as well.
Conversion will be with response design so you don't have to pay someone again in future to convert into response.
I have noticed the Sample conversion you have prepared is not responsive, so will not look nice on mobile.
Thanks in advance.
