Hey,
i'm negotiable.
I have experience with a lot of relational databases, database servers and other data containers.
This include interbase, firebird, mysql, mssql, microsoft jet (acces), dbf, xml, json, cvs, excel data, or maybe others i forgot to mention.
However this doesn't mean that i will be able to help you.
What i can say fr surely is that if your databases are one of these, then probably i can do it :)
Of course there can be other limitations, like for ex when the client data cannot be converted into the needed server data format, but i think it's not the case taking into account that your server database is under development too.
So please contact me so we can discuss other details. Depending on your needs i might modify my bid.
Eager to hear from you soon,
m.
