Situation
A close family friend who has given my brother a lot of photography work in the past offered me some work designing and implementing some new websites for a brand new business that she is involved with.
Working for her boss, I was to write 6 websites in wix for $150 each. No formal contracts were signed, and it was verbally agreed that after the first website was completed (1 - 2 days), I would be paid $150 and begin the second, then the third etc etc, until all websites were completed.
I began implementing the first website on the promise that she would send me the pictures, text and other information that I needed to complete it. I have completed 2 websites up to this point of needing the details to continue.
After months of waiting for the details, receiving the same "They are coming soon just be patient" reply, I have still not received these details. I have accepted that these details are never coming and would now like to be paid for the work I completed all those months ago. (2 x $150)
They have been incredibly slow and disorganized in their dealings with me, and I feel as though I should not have to wait any longer.
How do I tactfully ask for this payment, given that she has helped my brother in the past?
I'm worried that if I simply send an invoice this may be taken as rude and potentially strain our friendship. My job situation has since changed and I no longer have the time or need to complete the work, so continuing to wait for the delay to conclude and then finish the sites is not an option for me.
