Hi,
I understand that you are in a bit of a rush to get this through before the event is approaching. So, you can either choose to experiment with another bunch of novices and hope that the stuff gets completed before the campaign actually starts, or you can just hand over the responsibility of getting things perfected to us within the next few days with still some time to go for testing, fine tuning anything else and feeling at peace.
We are a team of experts with some of us having more than 15 years of working experience with PHP, API integration, etc. Additionally, we can work for 20 hours a day to ensure that work gets completed well ahead of time and you can get this off your table.
Now, it all depends upon you. Do you really want to keep on looking while we can actually just get the work done in the best possible way even before the timeline for this project bid expires?
Looking forward to your favorable response.
Best regards!!
