How to access HG sequence data?

[nospam at nospam.net]

Bac sequence is coming out for specific regions in drips and draps with
no discernible structure in place for readily identifying sequence from
regions of interest.  Can anyone give advise on the best way of
collecting new sequence information from specific chromosome locations?
Presumably, the best way of identifying the sequence is by Blast
searching with available marker sequence, but this seems to be time
consuming and tedious.  Are there available tools for automating this?

Thanks,
