I have been exploring family histories for many years as an keen amateur but I'm now retired and have now completed several courses on genealogy at Forth Valley College and University of Strathclyde as well as a Palaeography course at Glasgow University to build my expertise. I charge minimal rates as its not a full time business with premises etc and most charges are for access to the records that I would need to build your family tree or solve your challenge. . But all costs would be transparent and agreed before searching.
In addition:
As based in Scotland it may be possible to access local archives to build up your family tree and visit local area to take pictures or again access local records.( may be travelling costs for that)
I can search and build family trees for Scottish and Irish ancestors. At the outset, the Irish records are not always as straightforward as Scottish ones that are increasingly comprehensive but several databases can now be accessed in the public domain.
I can cover English and Welsh records if required as well as other countries if records are available.
