Hi! A local interior home cleaning company is planning on sending out raffle tickets to her clients. She has included in her raffle a very nice gift basket (full of goodies & treats) and a $100.00 gift certificate to be used towards her company cleaning business. She would like me to put something in - but I can't seem to think of what to put in - a gift certificate (say $50.00?) or a FREE service gift certificate (say residential aeration) or a buy something get something free/discounted type certificate. She does this every year and has good results from it. She has also teamed up with a lawncare company in Regina (SK, Canada) and they do the same sort of thing. Any help? T.
