Hi, I have very solid paypal skills. I have used all their APIs in over 100 different sites in past 8 years.
I have used their split payment APIs too like Adaptive Payments, several times.
Having worked in PHP for 8 years, I am familiar with all scripts and frameworks and custom coding.
I believe I am best suited for this job.
Paypal transactions can all be tested in sandbox mode. I have my own sandbox account and I can test paypal to paypal payments on it.
I can start right away.
Regards,
