Communicating with women for business purposes

Q: My items are advertised online and then shipped to customers. I do not have a physical store. I therefore communicate with customers, potential customers, suppliers, distributors and so forth via correspondence. These are often woman, almost always non-Muslim, from all different countries. I am a male. Regarding communicating with woman for business purposes:

1. Is it permissible to use formal business formalities/etiquette in email? For example, to say: "Good morning", "Hope you are well", "I look forward to your response", "It is a pleasure doing business with you", "All the best", "Kind regards" and so forth.

2. Is it permissible to communicate with them via the more 'informal methods' like SMS / WhatsApp / BBM / Facebook Chat / Twitter Direct Messaging etc.? I am mostly contacted via these methods initially.

3. If Question 2 is permissible: Can one use more informal terms like "Hi", "Hello","Thanks" and so forth when communicating over those mediums mentioned in Question 2?

4. Is it permissible to phone them and speak over the phone when necessary? In all the instances above, everything will be kept to the point of need and related to the business.

Facing difficulties

Q: What should I do? Everything I do in life is a failure. I have never had any success in my life. I feel helpless. I cannot provide sufficiently for my wife and child. We are bankrupt. Our business is broke. I am broke. Nothing is going the way it should. We read our namaaz, we pray to Allah asking for his divine intervention, but its as if Allah does not acknowledge us. We are in a lot of debt. I have given up, I feel like my only way out is death.

Scanning haraam items in a supermarket

Q: Is it permissible to work as a checkout/till operator in a big supermarket? Is my income Halaal? I have to handle Alchohol/Pork/Haraam Chicken and Beef to scan these items. I hold the very tips of the meat products so that I touch the least amount as possible. I have tried my best, my very very very best to look for alternative work but I just cannot find anything else. I ask Allaah to forgive me if I am doing wrong but this is the only success thatI have had job wise.

Free travel insurance with tickets purchased using a credit card

Q: If a person pays for a flight overseas with his credit card, the bank provides free travel insurance. Will it be permissible to use a credit card (which he keeps in positive balance so as not to get involved in credit but to get a good credit record) to purchase his flight tickets with the card with the intention of getting the insurance? If not paying with the credit card he would have to use cash or a debit card anyway.
