Hello, I am interested on your project, I must admit I don't know how to deal with transactions, but I'm very confident I can learn it fast, the rest shouldn't be very hard to do if at all.
I know my bid may not be very complete, I am new on the site, but I hope to begin working with you, if you're interested on giving me an opportunity just message me to discuss the details of the project.
Regardless of whether you award me the project or not, thanks for reading, and have a nice day!
