I dont think i can suggest myself here, but for starter maybe you can contact @Ai chan for holding hands first
above 17 yrs old? will grannies do? cause my nemesis moms grandma needs a new partner as her recent one died due to old age(rest his soul)
Still need info about the "payment". Well, I guess you can discuss that "privately" with the "partner".
No seriously..... Even posting it on FB or twitter or heck even reddit would have been more effective than posting it here
Then you need to post the "bait" here, before going onto the "series discussion", like an estimate of "At Least" how much you are willing for the "payment", then "privately" discuss the "full amount of payment" later.
So, is this part of the drama development where your father wanted to see you get marry as soon as possible because 1) He's dying and wanted to see you married before he died. 2) You're getting an inheritance but only if you got married before certain age. So much contract marriage plot development here. Edit: What's next? Pay the partner to be a legally wedded wife, but will agree to divorce after a while and you'll both go your own ways. Only to later realize that you're both meant for each other and wanted to stay together etc.
