Hi there, not sure how much traffic your sites have, but you may always try
Interserver and their VPSs
I think you should be able tu run your network with their VPS for around 30-35 usd per month. Check out their "slices", you may start from 1 slice and upgrade slowly. I think their cheapest semi managed linux vps is for around 15 usd/ month. For around 30 usd/ month you get a decent machine with 8 GB and 4 cores..with cpanel or directadmin as you like.
Upsides:
- reliable
- not expensive
-fast
- overall without issues, especially if you can do some easy unix tasks by shell
- over 99.5 % uptime?
Downside:
- fast/very fast but kind of clueless South Asian support. Sometimes you need to repeat to make them understand the problem. The owner/ CEO / managing boss is an American though
I would never host my sites at Namecheap or any other domain provider, never put all eggs into one basket...
