Received this text:  "Hi I would like to know if I can get free estimate for my windows upgrade?, also do you accept credit cards?"  Typical message that I get on almost a weekly basis...the grammar and punctuation scream non-English speaker, and at the end is always the "do you take credit cards" part.  Sometimes they are looking for "detailing", sometimes it's "home windows",  but it's all a scam.  They say whatever price you quote is great, they'll give you a (stolen) credit card number to pay and tell you to charge twice as much, then just send them back the difference through some kind of money wiring service.  I used to ignore these, but now I have some fun with them by profanely acknowledging them as an illiterate scammer.
