Hi Tim,
Nice little project and a nice business your wife has :) I would really like to help you with this, although it's not 100% clear to me exactly what you need to be moved (as you say you can move some yourself), but as a native English speaker it will not take me long to figure it out once I speak to you.
Just had a look at SquareSpace and it looks really interesting. Although I have never used it before, so I will create my own account to use as a Development Account to test the move. This will also save your 14 day trial for when we can guarantee a successful move, which I think you will appreciate.
If I am unable to deliver your project within the time I will return 50% of my bid.
I can call you if you want to speak to me, but I would really like to talk to you if possible. I can call land-lines and cell-phones in the US for free :)
Anyway, if you are bored of the generic replies from others, I hope you will take a chance with me.
Looking forward to hearing from you.
