someone asked me for a quote for a job. I emailed her a quote. she replied back that this was for a client and she needs to ask her and get back to me. 2 days later, she emailed back that she was ready to proceed. She said I have credit card info ready, let me know what i need to do. because the amount was large by my standards, I didnt really want to take credit card, for 2 reasons: fees would be too much, and I dont like chargebacks. so I replied back "if payment is by credit card, I will have to send you a 3 page agreement, which your client will have to sign" I also said "I will need pictures of the front and back of the credit card." The reason I said all this is to make it too hard for her to use a credit card, to pursue her to send a check. Then at the end of the email I said "we also accept checks and money orders." She emailed back "I will talk to my client and get back to you" This was last thursday and I still haven't heard back. how can I push her to convert ASAP? should I email and say "this price is good for a limited time, it will increase soon" or is that too obvious?
