We use a company on a contract basis - best decision I ever made. They always have engineers in the area. Paralogic Networks. Contact [email protected] - 01844 293 333
We pay them to come once a month and sort out all the issues.
If you haven't sorted this already you might want to contact me on 0207 554 9979. I work for The TI group and we are just opening a new office in Marshalsea Road, Borough. We are a well established IT services provider and offer flexible IT support options. Rather than going with an independant expert, who will be on holiday or sick at some stage, if you deal with a company you are assured of help when you need it. If you are interested let me know and I will come along to meet you and we can decide how best to address your IT requirements.
