Hello there,
I would like to work with you on this project. I'm a highly experienced web developer, with a great PHP skillset. I have allowed 4 days, in case I run into any problems along the way, but i would look to have the project completed as soon as possible.
Can you tell me was the link working OK once before?
If so what has changed, do you know of anything major between it working and now not working, or has it just happened 'out of the blue'?
These would be useful questions to have answers to, but regardless, I will find out what is wrong with the interaction, providing they are compatible and come up with a great solution for you.
